Silverstein's cover of OneRepublic's "Apologize" has been made available on the official MySpace for Punk Goes Pop 2, due out on 10 March 2009 through Fearless.
I agree, though I'm thinking they could've actually done without the screaming, for once. I'm surprised they didn't release Mayday Parade's cover first, considering they're signed to Fearless and all.
Not directly related to Silverstein, but it's on the topic of Punk Goes Pop 2. August Burns Red's cover of Hit Me Baby One More Time has been uploaded to the PGP2 Myspace. It's pretty awesome.
