A commercial for the new Prius came on TV, using an a capella cover of "Let Your Love Flow".  I thought I'd see if it was something that was made especially for the ad, or if it was an existing cover they used. So, I fired up iTunes and searched. I learned two things.

1. I'm pretty sure the song in the commercial is one made especially for the ad.
2. I've discovered an entirely new context for "let your love flow".
