E-music discovery & purchase. I listen to satellite radio in my car and often discover new music. I constantly want to purchase new music I hear, but I can't write down the info while I'm driving. The connection I'm looking for is a button on the satellite radio that would send me an e-mail with the artist info. The E-mail could also contain a link to Amazon.com/iTunes store to purchase the music. The satellite service is already communicating with my receiver and the satellite provider could certainly use the additional revenue stream from the click through.
