Jimmy Eat World stuff is good. They really should just put out all of Bleed American.

I saw Jimmy Eat World live not too long ago at a festival.... That one song is good.

Many people will remember Trippin' on a Hole in a Paper Heart being in Guitar Hero 2 (in cover form). Brings back some good memories :)
 
Stone Temple Pilots? Eff. I could not be happier. While I would have liked more songs Purple and Tiny Music', like Army Ants and Big Bang Baby (and I find Creep an odd choice for a band game), just so happy we're getting more STP. A truly underrated band. Hopefully they get the Pro Guitar treatment soon, would happily pay more for that.
 
Bleed American? I understand it's already in GH5, but isn't that song called Salt, Sweat & Sugar? At least, that's what my copy of Bleed American calls it :/

Sweet my favorite song on Inverted. Fucking love Jew, I'd love to see Always Be and Here it Goes, hell all of Chase this Light.

Might pick up a few of the STP tracks. Don't like Jimmy Eat World, though Pain is a bit of a guilty pleasure song for me, but I blame Midnight Club 3 for that.
