When I get songs stuck in my head, they sometimes mix together to form a really strange song, but the main songs are:
I wanna see you, but I don't wanna see you (RIKU+ID)
Etude (Cains:Feel)
Vanilla
Current, Transient, Creeper, and Last Hallucination (Schwarz Stein)
Kasumi, Cage (DeG)
What can I do (FLAME)
Ma Cherie (Malice Mizer)
It is kinda scary for everyone around me when I run down the road singing "I wanna see you but I don't wanna see you" at the top of my lungs, and yelling for help to get them out of my head when I stop for breath....
