I know that there's a huge debate about whether bands letting their songs be used in commercials is "selling out." And I have been appalled by this practice in a few instances -- "Lust for Life" being used to sell Jaguars comes to mind. But mostly I think it's awesome; I love hearing songs I like on tv, especially when they're by bands that don't get played on the radio.
So, I've been amused to hear the New Pornographers' song "The Bleeding Heart Show" on commercials for the University of Phoenix lately. Of course, they don't include any of the words, so we don't get to hear Neko Case singing.
