Gamespot had an article about a new game from Harmonix for iPod called Phase. It's pretty much Frequency/Amplitude for iPod. It comes with some songs such as the Harmonix staple Freezepop and a few others as well. The best feature is you can use any song you have in iTunes and play it in the game. I just played a few songs and had a lot of fun. Easy and Medium weren't too difficult, but I failed on my first attempt on Hard. The game is only $4.99, so if you're looking to add a quality game to your iPod, you might want to try this out.
