Rock Band is a favorite around BGR World Headquarters, so we were quite pleased to see the following bit of news. The Rock Band online store has finally gone live, albeit only for our Playstation 3-toting brethren. The store features a large amount of downloadable content, sporting tracks from artists such as Nine Inch Nails, Oasis, The Police, and more. Tracks are $1.99 each, with a number of special "Track Packs" available for $5.49. The downloading process is a bit cumbersome, and requires a PS3 running OS 1.03, but it’s certainly worth checking out.
