Clear Channel along with Frontline Management have teamed up to bring you Sirius XM radio channels that are based on big time artists. You can now have a channel where it plays artists like Eagles, Christina Aguilera and Weezer. In addition to each artist having their own channel it will play their own recomendations and similar artists. Sounds a lot like recomendation engine based radio to me. Where could they have gotten that idea from?
