Couple of fun/interesting/hatstand Japanese filmy suggestions:
Survive Style 5+ (soundtrack to this is AMAZING, much better than any film featuring Vinnie Jones has any right to be. It's also 100 quid+ on CD)

Electric Dragon 80,000v (soundtrack provided by the film's director's band, also featuring the star Tadanobu Asano - and yes, I know that the soundtrack CD came with the DVD but it didn't have this bloody track on it...)

EDIT: Versus is also a contender, killer soundtrack even if a fair portion of it (sadly not during the attached trailer) is extensively sampled from Squaresoft games - Legend Of Mana's soundtrack being a particular source...
