I'd say the 4th CD will have the USA singles which are (correct me if I'm wrong):

1. Torn
2. MOP
3. WTLF?
4. One
5. Are You Ready? (I believe)
6. What If
7. WAWO
8. Higher
9. Bullets
10. OLB
11. MS
12. DSD

They will probably have YGO, ITTE?, BAT, and TWIMC on the CD and maybe a couple of new ones, but that would be a long CD, and might not fit... I'm sure Wind-Up probably wants to fill the CD up though.
