We all heard about Terrestrial Radio's latest multi-million dollar ad campaign, stating that with "Radio, you hear it here, first" - well, XM Satellite Radio has fired back with "XM, you hear it here, best."

The latest in the battle between terrestrial and satellite, XM pointedly raises the perverbial middle finger to terrestrial by saying "Not Only Do You Hear It Here First, It's Commercial Free" and featuring Ludacris, Ashanti, Alicia Keys, Hoobastank and Avril Lavigne right on the Hear It Best page. The same artists who are featured in the Hear It First radio commercials.
