Most epic remix:
YouTube - ill skillz- i'll be there 4 u (concord dawn remix)
Most epic never get-sick-of-song:
YouTube - The Mars Volta- Cicatriz ESP
Most epic sexy-song-that-doesn't-seem-sexy-inthe-song-but-actually-is-lol:
YouTube - Bodyrox feat. Luciana - Yeah Yeah (Clean Version) (that's the clean version... in the real version they're dry humping everywhere with their shirts off xD)
That's all I can think of right now.
