While Christmas shopping a few weeks ago, I walked through a number of electronics and entertainment stores (BestBuy, Circuit City, etc.). It seems pretty obvious that Rock Band is the current winner of the "battle" of the music video games.

Every store that I went into had Guitar Hero: Aerosmith on sale for 50%+ off of its regular price. On the other hand, I'm receiving what seems like weekly emails from Rock Band as they add new artists to the Rock Band store. These artists range from Roy Orbison to Dead Kennedys, Motorhead, Testament, At The Gates, Mission of Burma and many other eclectic, non-mainstream artists. There is something to be said for having this much flexibility in customizing your music game...and I'm particularly enjoying being able to play Burma's "That's How I Escaped My Certain Fate" and At the Gates' "Blinded By Fear" back-to-back.

The Rock Band store is now has more than 500 tracks and has had over 30 million paid downloads to-date. Here is the link to the list of all of the songs available for Rock Band.

Harmonix Music Systems' big release for next year is going to be a new standalone game based on the Rock Band premise that features the music of The Beatles. The unnamed game will feature "a visual and musical history of the Beatles, and will include the United Kingdom-released versions of songs from their albums Please Please Me through Abbey Road." While this game will not be part of the Rock Band series, all Rock Band accessories are supposed to work with this title.
