Here's a puzzle in a series that I started on another forum.
The puzzle requires 2 answers:
1. The solution of the Zero-X-Killer on top.
2. The name of the album below the killer.
I removed artist and title, so you have to browse your CD collection to find it. It was released in 1996.
The killer is Ruudiculous until proven otherwise...
3x3:d:k:4864:4864:5634:56345381:5381:4871:4871:48643594:563453812319:4871:4370:43705634:22:53815657:5657:4370:28:29:30:31:32:33:34:565737:38:39:40:41:42:43259647:48:49:50:513372:4150:4150:4150:57:58:59:4668:4668:4668:5439:41502369:6211:5444:5444:46685439:54396211:6211:6211:5444:2631
Happy hunting and killing!

Sorry, can't help you with the album, I'm not a music freak. But here is the walkthrough for the Album Killer (in tiny font). That was a real tough nut, Ruud.

OK finally got around to finishing it - quite a challenging one.
Posting my walkthrough as there are a few minor differences from [edit] Peter's (oops! - should take a closer look before I post!) - mainly the same through the opening game but a bit different in the middle-game.
1. 45 on n7 - r8c4=1
2. 45 on n9 r8c6=4
3. 45 on r89 r8c28 total 5 = {23}
3a. naked {23} in r8c28 for r8
3b. no 2/3 at r3c2 r3c8 r5c5
4. 9(3) n78 can only be [531]/[621] r9c3={23}
4a naked {23} at r8c8 r9c3 for n7
5. 21(3) n89 can only be 4{89}
5a. {89} locked in 21(3) for n9 and c7
6. 9(3) in n3 - only combo with 4 is {234} - no 4 in r23c7
7.1 only found in r7 in n7
7a 1 locked in 16(3) n7
7b remove from 18(3)n9 in the same row
7c 1 locked in 10(3)n9
8. 10(3) n9. only allowed combo 5{14}/6{13}/7{12} - no 5/6/7 in r9c89
9 must use 7 in 21(3) n7= - 7 locked for n7
10. only combos for 16(4)n7=2{149}/3{148} - no 5/6 in 16(4), must use 4
10a reasoning - can't use {1258}/{1456}/{2356} because it would break the 9(3)n78
11. 4 locked in 16(4)n7 for r7
11a. 4 locked in 10(3)n9 = 5{14} -> r8c3=6 -> r9c4=2 -> r8c2=3 -> r8c8 =2
12. 16(4)n7 = 3{148} - {148} locked for r7
13. 21(3)n7 = {759} with 5 locked for r9
14. 18(4)n9 = 2{367} - {367} locked for r7
15. 24(4)n8={3678}
16. unmarked 16(3)n8 = {259}
17 must use 9 in 22(3)n36 - no 9 in r4c8 r12c9
18 45 on r123 - r4c19 minus r3c5 = 14
18a max r4c19 is 17, so max r3c5=3 ={123}
18b min r3c5 is 1, so max r4c19 is 15 = {69}
18c. r4c19 both limited to {6789}
19 45 on n2 - r1c37 minus r3c5 = 4
19a. 1/2/3, so r1c37 total 5/6/7
19b. no 7/8/9 in r1c3, no 7 in r1c7
20. 19(3)n3 - no possible combo with 3/6 in r1c8
21. 45 n1 r4c1 minus r1c3 equals 5
21a. r4c1 = {689}, r1c3 = {134}
22. 45 n3 r4c9 minus r1c7 equals 5
22a. r1c7 = {1234}
23. 22(3) n36 - no combo with 8 in r3c8
24. 17(3) n14 - no combo with 8 in r3c1
25. 19(3)+9(3) in n3 - no valid combination with 5 in r2c7
26. 19(3)+14(3) in n1 - must use 8 in one or other - no 8 in r3c2
27. 4 locked for r3 in c1-4, all cells can see r1c3,so no 4 in r1c3 -> no 9 in r4c1
27a. (from 18) r4c19=[69]/[87]/[89] - no 6/8 in r4c9 - no 2 in r3c5
27b. (from 22) no 3 in r1c7
27c. (from 19) r1c37=[14]/[32]/[34] - no 1 in r1c7
27d. no 1 in 17(3)n12
28. 3 locked in n3 for r2
29. must use 1 in 9(3)n3={126}/{135}
29a 19(3)n3 combo {568} would conflict with 9(3)n3 - no 5 in r1c8
30. 22(4)n12 - no 3 in r123c4
31. 19(3)&14(3)n1 - {13} in r1c3 restricts combination with 3 at r1c1
32. 14(3)n1 must contain 1 when r1c3=3 and must contain 3 when r1c3=1 - {13} locked in 14(3)+r1c3
32a. 3 locked in n1 for c3
32b. 3 locked in 10(3)n4 = {136}/{235}
32c. 17(3)n12=6{29}/8{27}/8{45}/6{47} - no 6 in r3c12
33. 9(3)&22(3) n3 must use 1,5,6,9 - no 6 in 19(3)n3
34. Placing 1 at r2c5, r2c6 or r3c6 eliminates all possibles for 1 in row 1 (r2c5=1 -> r3c5=3 -> r3c3=1 -> r1c3=3)
34a no 5 in r1c5
35. 4 in r1 can only be at c5 or c789
35a. n3 - 4 in r1 or 4 in r2c9 -> r1c7=2->r1c5=4
36. 19(3)n1 - no 7 in r2c1, no 5 in r1c2
37. cannot place 7 at r4c9
37a r4c9=7 -> r1c7=2->r1c3=3 -> r3c5=1 -> no valid combo in 6(2)n2
37b. r4c9=9 - 22(3)n35=9{67}/[58] -> unmarked cage=23(5)n6
37c. only value 9 at r1c8 n3
37d. 19(3)n3= 9{28}/[73]
37e. only value 4 at r1c7n3
37f. 6(2)n2=[15]/[24]
38. 8 locked in n3 for c9
39. 19(3)&14(3)n1. Only valid combos remove 2 from r2c1, 5,8 from r2c2 8 from r2c3 5,8 from r3c3
39a 8 locked in 19(3)n1
40. (from 19) r1c3=r3c5
40a. r1c3=r3c5=1 -> 6(2)n2=[24]
40b. r1c3=r3c5=3 -> 6(2)n2=[24] since 1 must be used in the 21(4)
40c. 6(2)n2=[24]
41. 19(3)n3=9[82]/[73]
42. 19(3)n1={568} - locked for n1
42a. 14(3)n1=4{19} - {19} locked for r2,n1
42b. 17(3)n14=8{27} - {27} locked for r3
42c. r1c3=3 -> r3c5=3
42d. 22(3)n3=[589]
42e. 19(3)n3=[973]
43. 22(4)n12=3{568} {568} locked for r4 and n2
43a. 21(4)n23=[4179]
43b. 9(3)n3=[261]
44. 23(5)n6=8{1356} r5c8=8
. . . and it all unravels fairly quick from there with singles and cage sums

Posting my walkthrough as there are a few minor differences from [edit] Peter's (oops! - should take a closer look before I post!) - mainly the same through the opening game but a bit different in the middle-game.
1. 45 on n7 - r8c4=1
2. 45 on n9 r8c6=4
3. 45 on r89 r8c28 total 5 = {23}
3a. naked {23} in r8c28 for r8
3b. no 2/3 at r3c2 r3c8 r5c5
4. 9(3) n78 can only be [531]/[621] r9c3={23}
4a naked {23} at r8c8 r9c3 for n7
5. 21(3) n89 can only be 4{89}
5a. {89} locked in 21(3) for n9 and c7
6. 9(3) in n3 - only combo with 4 is {234} - no 4 in r23c7
7.1 only found in r7 in n7
7a 1 locked in 16(3) n7
7b remove from 18(3)n9 in the same row
7c 1 locked in 10(3)n9
8. 10(3) n9. only allowed combo 5{14}/6{13}/7{12} - no 5/6/7 in r9c89
9 must use 7 in 21(3) n7= - 7 locked for n7
10. only combos for 16(4)n7=2{149}/3{148} - no 5/6 in 16(4), must use 4
10a reasoning - can't use {1258}/{1456}/{2356} because it would break the 9(3)n78
11. 4 locked in 16(4)n7 for r7
11a. 4 locked in 10(3)n9 = 5{14} -> r8c3=6 -> r9c4=2 -> r8c2=3 -> r8c8 =2
12. 16(4)n7 = 3{148} - {148} locked for r7
13. 21(3)n7 = {759} with 5 locked for r9
14. 18(4)n9 = 2{367} - {367} locked for r7
15. 24(4)n8={3678}
16. unmarked 16(3)n8 = {259}
17 must use 9 in 22(3)n36 - no 9 in r4c8 r12c9
18 45 on r123 - r4c19 minus r3c5 = 14
18a max r4c19 is 17, so max r3c5=3 ={123}
18b min r3c5 is 1, so max r4c19 is 15 = {69}
18c. r4c19 both limited to {6789}
19 45 on n2 - r1c37 minus r3c5 = 4
19a. 1/2/3, so r1c37 total 5/6/7
19b. no 7/8/9 in r1c3, no 7 in r1c7
20. 19(3)n3 - no possible combo with 3/6 in r1c8
21. 45 n1 r4c1 minus r1c3 equals 5
21a. r4c1 = {689}, r1c3 = {134}
22. 45 n3 r4c9 minus r1c7 equals 5
22a. r1c7 = {1234}
23. 22(3) n36 - no combo with 8 in r3c8
24. 17(3) n14 - no combo with 8 in r3c1
25. 19(3)+9(3) in n3 - no valid combination with 5 in r2c7
26. 19(3)+14(3) in n1 - must use 8 in one or other - no 8 in r3c2
27. 4 locked for r3 in c1-4, all cells can see r1c3,so no 4 in r1c3 -> no 9 in r4c1
27a. (from 18) r4c19=[69]/[87]/[89] - no 6/8 in r4c9 - no 2 in r3c5
27b. (from 22) no 3 in r1c7
27c. (from 19) r1c37=[14]/[32]/[34] - no 1 in r1c7
27d. no 1 in 17(3)n12
28. 3 locked in n3 for r2
29. must use 1 in 9(3)n3={126}/{135}
29a 19(3)n3 combo {568} would conflict with 9(3)n3 - no 5 in r1c8
30. 22(4)n12 - no 3 in r123c4
31. 19(3)&14(3)n1 - {13} in r1c3 restricts combination with 3 at r1c1
32. 14(3)n1 must contain 1 when r1c3=3 and must contain 3 when r1c3=1 - {13} locked in 14(3)+r1c3
32a. 3 locked in n1 for c3
32b. 3 locked in 10(3)n4 = {136}/{235}
32c. 17(3)n12=6{29}/8{27}/8{45}/6{47} - no 6 in r3c12
33. 9(3)&22(3) n3 must use 1,5,6,9 - no 6 in 19(3)n3
34. Placing 1 at r2c5, r2c6 or r3c6 eliminates all possibles for 1 in row 1 (r2c5=1 -> r3c5=3 -> r3c3=1 -> r1c3=3)
34a no 5 in r1c5
35. 4 in r1 can only be at c5 or c789
35a. n3 - 4 in r1 or 4 in r2c9 -> r1c7=2->r1c5=4
36. 19(3)n1 - no 7 in r2c1, no 5 in r1c2
37. cannot place 7 at r4c9
37a r4c9=7 -> r1c7=2->r1c3=3 -> r3c5=1 -> no valid combo in 6(2)n2
37b. r4c9=9 - 22(3)n35=9{67}/[58] -> unmarked cage=23(5)n6
37c. only value 9 at r1c8 n3
37d. 19(3)n3= 9{28}/[73]
37e. only value 4 at r1c7n3
37f. 6(2)n2=[15]/[24]
38. 8 locked in n3 for c9
39. 19(3)&14(3)n1. Only valid combos remove 2 from r2c1, 5,8 from r2c2 8 from r2c3 5,8 from r3c3
39a 8 locked in 19(3)n1
40. (from 19) r1c3=r3c5
40a. r1c3=r3c5=1 -> 6(2)n2=[24]
40b. r1c3=r3c5=3 -> 6(2)n2=[24] since 1 must be used in the 21(4)
40c. 6(2)n2=[24]
41. 19(3)n3=9[82]/[73]
42. 19(3)n1={568} - locked for n1
42a. 14(3)n1=4{19} - {19} locked for r2,n1
42b. 17(3)n14=8{27} - {27} locked for r3
42c. r1c3=3 -> r3c5=3
42d. 22(3)n3=[589]
42e. 19(3)n3=[973]
43. 22(4)n12=3{568} {568} locked for r4 and n2
43a. 21(4)n23=[4179]
43b. 9(3)n3=[261]
44. 23(5)n6=8{1356} r5c8=8
. . . and it all unravels fairly quick from there with singles and cage sums
