All you need to know about me, distilled into one mix CD I made for myself:

Track 1 - Crystal Energy, Kuribayashi Minami (who got her start in more mainstream music by... doing voices in porn)
Tracks 2-8 - Nakayama Arisa songs (including Heart to Heart, the opening to a game that started on the PS2, then was ported to the PC with added porn0
Track 9 - Disillusion, Tainaka Sachi (the opening to Fate/Stay Night, originally a porn game and now a wildly popular TV series)
Track 10 - Being, KOTOKO (who, if you pay attention to my rants, still writes music for porn along with topping the charts every once in a while)
Track 11 - Spiritual Garden, Tamura Yukari (which is the theme to a show that's a for-children spin-off of a porn game)
Tracks 12-13 - Selections from Purple Rain, Prince (hey, at least it wasn't Erotic City)

And this was without even thinking about it.
