Still counting the days until Guitar Hero III or rival Rockband appears in time for Christmas? Then check out Guitar Hero Encore: Rock the 80s. It's a bit pricey at $50 for 30 new songs, but if you want to rock out to hits from your youth, it's a must have. The song list includes: We Got the Beat, I Ran (So Far Away), Radar Love, Turning Japanese, What I like About You, Synchronicity II, Ballroom Blitz, Lonely is the Night, Heat of the Moment as well as tunes from Poison, Anthrax, Twisted Sister and Judas Priest. However, some of the songs are really more keyboard oriented than riff rock anthems. I don't think anyone ever air guitared to Flock of Seagulls before.
So get out the spandex, put on some hairspray and rock like you never did before. Available for Playstation 2 only. Though I would guess these songs will end up on XBox Live for download at some point.
Note also: Guitar Hero III will be coming out for the PC and Mac this fall.
