Artists such as 3 Doors Down, Army of Me, Colbie Caillat, Clique Girlz, Sheryl Crow, Flipsyde, Lady Antebellum, Mere, Nelly and Kate Voegele are putting together a compilation of songs just in time for the Olympics that will play on NBC and Telemuno during broadcasts of the games. The songs are supposed to be like a work-out mix that motivates the U.S. team to run faster, jump higher, etc. But the songs will also be for sale to consumers on AT&T’s (NYSE: T) Web site or mobile phones and at NBCOlympics.com during the month of August. There’s no word on how much the special tunes will cost, but the proceeds will go to Team USA. In addition to full tracks, AT&T users will be able to buy ringtones and ringback tones based on the songs. Other artists are expected to be announced later. This may be a great way to get people of all demographics interested in downloading music to their phones, however, it will take at least one hit among the tracks in order to really drive that kind of adoption. Of course, AT&T’s tie to the games is that they are the official sponsor, and official telecom sponsor, of the U.S. Olympic Team for the 2008 games in Beijing. Release.
