The Revenge of JB

Tap Tap Revenge might just be one of the best series of iPhone/iPod Touch apps available. And it just got better. Justin Bieber's "My World 2.0" now has its very own Tap Tap!

Justin reached out to fans recently, and gave them the ultimate challenge: "Bieber Revenge…get tapping to songs from MY WORLD 2.0! let's see if you can beat my score!" Think you've got what it takes?

If you haven't Tap Tap'd before, you'll catch on pretty quickly. The set up looks a lot like Guitar Hero. Once you select a song, you have to hit the right notes at the right time in order to rack up points. The harder levels require you to use all of your digits, so don't get tripped up by your own fingers!

What's your best score so far on "Baby"?
