File this one under "A pleasant surprise, but not quite what I had in mind." Harmonix has released their portable rhythm action game, Phase: The Music is Your Game onto iTunes. The $4.99 iPod game lets you use your own music tracks as the game's soundtrack, and looks similar to other Harmonix titles like Frequency and Amplitude.

The game is played by using the iPod wheel to match (or catch) discs as they come towards you onscreen. Like Guitar Hero, there seems to be some kind of bonus/multiplier for nailing phrases, which I'm assuming must be done in-time with the song's rhythm. You know, "the music is your game" and all. 

Silly title aside, $4.99 isn't a bad price for what seems like the spiritual successor to some of Harmonix's past music titles. You know, before all of this peripheral tomfoolery. If I had an iPod, I'd be sure to check it out. But since I don't, who's going to do the dirty work for me?
