Rock Band discs always include some songs you probably aren't familar with, but you end up really liking, and for me, Paramore's "CrushCrushCrush" was one of those. However, I didn't buy their 2009 album, Brand New Eyes, so I'm not familiar with the three new Paramore tracks that Harmonix has added to the Rock Band Music Store starting today.
Okay, obviously I've heard "The Only Exception," but not the other two tracks: "Ignorance" and "Brick by Boring Brick." But all three are in the store as of now for $2 each, or $5.49 for the Paramore Pack 01. All the songs have keyboard parts, but only "The Only Exception" has the optional $.99 Pro Guitar and Pro Bass upgrades.
