As I redo my library pretty often, this is only recently. But it is:
1.
ayu - Microphone
2. Kana Nishino - Best Friend
3.
ayu - count down
4.Kana Nishino - Yours only
5.Kana Nishino - Dear..
6.
ayu - Last Links
7.
ayu - Don't look back
8. Sys Bjerre - Pik
9. ALI PROJECT - Gokuraku Ibarahime
10. Shakira - Te aviso, te anuncio (tango)
Wow o.o I thought it would be totally filled with ayu and Shakira.
Okay, I was wrong. xD
