I received an iPod Touch 2g for Christmas, I got the free "Tap Tap Revenge" App and liked it a lot. Tap Tap Dance is #1 and Guitar Rock Tour is #2 on the music games top free apps list. I was wondering which one is better overall? I was also wondering if you could get additional tracks for either of the games? Tap Tap Dance is $4.99 Guitar Rock Tour is $5.99 I prefer the songs that are on Guitar Rock Tour but game play matters a bit more. I was also wondering if "Christmas with Weezer" is any good? It's on sale at the moment for $1.99. I really like Weezer's music. Please post what you think I should buy. Thanks!
