Electric Light Orchestra, "Last Train to London"
What's not to like?

Harry Belafonte, "Jump in the Line (Shake, Senora)"
A wonderfully energetic and rhythmic calypso jam about a lady dancer,"Senora." "When she wind up she bottom, she go like a rocket!"

Beyoncé, "Crazy in Love"
Beyoncé delivers such power and presence in her performance, and with a song this good, you can't not dance. Plus, it features Jay-Z...I know, right!?

Daft Punk, "Digital Love"
U.S.E never would have existed without this song.

Underworld, "Pearl's Girl"
A complete rave/transcendental/astral projection experience in 10 minutes.
