Facebook, the MySpace of the EDU world (and the 7th most trafficked site in the US), has announced a back-to-school promotion involving the iTMS and 10 million music samplers. They will be giving away 1 million 25-song samplers each week for the next 10 weeks, with genres including Alternative, Rock, Hip-Hop and Electronica. It appears that one only needs to visit Facebook to see banners like this, which are linked to the download at Apple's site, so go forth and download, iTunes and Facebook users.[via iLounge]
