Hey Kangaeru,
Ok, many great one's have been mentioned. High energy right?
Darius Rucker - Wild One - is a good way to start it off. Not high energy but upbeat and certainly sugestive
Goldfrapp - Strict Machine and Twist - two sexy songs
Prodigy - Firestarter (Empirion Mix) - I love the way it builds up and it's 8 min long (which is a bonus). Ironically I like to kickbox to this song.
Massive Attack - Angel - once again, great buildup, very moving.
Smashing Pumpkins - The Everlasting Gaze - very high energy, would be a perfect song if it wasn't for the cruel interuption by Billy's voice near the end.
BT & Sarah Mclachlan - I Love You - I adore this song, it's high beat, low energy, slight ups and downs, 9 min long, it's really wonderful.
Sasha and John Digweed - Last Train To Lhasa - 11 min long, high beat, very steady, great to get lost in.
Also try some songs by Underworld - Cowgirl, Twist, Born Slippy
Juno Reactor (notable for their Matrix songs) is sweet if you like that kind of music.
Cheers.
