Song Parodies

Thought I'd put it in here rather than Entertainment as it's not a serious topic.

As the title states, this is a thread for song parodies! Shock horror.

Obviously Weird Al is one of the main pioneers in the field, but I want as little of him as possible. Rather, parodies from groups or people others might not have heard of are preferrable.

I'll start the ball rolling with a parody from Chris Moyles (from the Radio 1 breakfast show):



It's a parody of La Roux's Bulletproof:

A Jay-Z instrumental with T.I. running smack on Lil Flip.
