I'll get Black Crowes, but where the hell is Soundgarden? Seriously, first album in 15 years...we should have gotten launch tracks to commemorate that. Come on Harmonix, I need some Bones of Birds!
There are already 10 Soundgarden songs in the game. I'm sure more wouldn't be unwelcome but you're not hurting for opportunities to play them.
The Miley Cyrus pack was released same day as Can't Be Tamed (the album). Similar thing happened with the H.I.M. pack. It happens a lot more often than you'd think, but it hasn't happened as much with post-RB3 DLC. At least it seems that way without actually doing the math.
I get them all. :D
