the Propel fitness water one where the woman is power walking thru Hollywood (John Stamos cameo) and turning heads to MJ Blige, and then she "wakes up" in her own neighborhood. Good one:

Then the other, where the woman runs alongside the car playing her tunes and the car goes down stairs, etc, skipping the music. I think it's just an ad for an ipod or something, but like that one too!
