I've never seen Initial D, but I like the group MOVE who's done some songs for it. The first song I fell in love with by the group was DOGFIGHT, which made me a fanatic of them. Later, I found out it was the Initial D Fourth Stage Opening and how quite a few other songs by them was used in the series.
Interesting, though. When I do think of Initial D, I think of games.
MOVE did some of the openings/endings for each stage.
Around the World (Initial D First Stage Opening 1) Rage Your Dream (Initial D First Stage Ending 1) Break In2 the Nite (Initial D First Stage Opening 2) Blazin' Beat (Initial D Second Stage Opening) Gamble Rumble (Initial D Third Stage Opening) DOGFIGHT (Initial D Fourth Stage Opening) Blast My Desire (Initial D Fourth Stage Ending)
That's all that comes to mind for me right off for openings/endings the group has done. I could've missed some, but, for the record, I keep up with the group's music more so than what songs were used for what. Still disliked their latest album, though. ;_;
