"We've been really pleased with the continued performance of Rock Band downloadable content. We've delivered over four years of weekly DLC and over 3500 songs for the music platform, and we have no plans to stop weekly releases any time soon. Fans can tell us what songs they want by visiting our new Rock Band Dashboard Facebook App and voting for their favorite artists using the built-in Wishlist feature." - Harmonix director of communications John Drake

I can count the number of Rock Band songs I've downloaded on one hand, but I guess I'm in the minority on this one!
