Tunes...

[bungle]

Street Fighter 2 character select screen
Guiles theme from SF2
Resi 2 in general

Had to add them in.

[Bleeders]

Secret of Mana - theres a giant skull & hands boss in the game somewhere and the tune to him was quality.

Aah yes...Thanatos, that was a good tune.

But as for the topic in hand, I'd have to say anything from Metal Gear Solid 2 or Initial D.

[Trok REAPER]

Magical Sound Shower - Outrun

Chrono trigger soundtrack and (probably cause some frowns) FF8 but I havent played any of the others so I dont know if the tunes are rehashed at all. Oh yeah that giftpia theme tunes pretty awe inspiring too!
