Bajofondo y Julieta Venegas – "Pa' bailar"

There are crisper versions of the video out there featuring the instrumental version, but I like Julieta Venegas' vocal. Bajofondo member Gustavo A. Santaolalla has also put together some great film soundtracks and scores, winning Osars for his fine work on Brokeback Mountain and Babel. (Thanks to Buck for the video assist.)
