The original version of La Ritournelle (which is French, bien sur, for "The Ritournelle") was on Sébastien Tellier's Politics, released in 2004. It tricks you into thinking it's an instrumental track - a good one - and then after four minutes, the vocals appear, along with the light funk. It's worth the wait, and the wait is worth it.
