I'm just curious as to whether or not anyone else has learned of a great song and/or band because of them being used for commercials. It has happened to me several times. "1234" by Feist (Leslie) and several others. The latest is the new Heineken ad done to a live performance of "Golden Age" by the Galaxy Asteroids Tour. The weird thing about that is that I was familiar with Leslie Feist from her work with "Broken Social Scene", but didn't realize that she had a solo career as well.
