Beats

It's taken longer than expected, but Beats brings Frequency/Amplitude-style gameplay to the PSP, allowing for beat-matching button-mashing on the go. It's not a port though. Instead of hitting notes on music tracks, players need to match button presses as they pass over one of three spots on the screen. At higher skill levels, highlighting which spot you're matching beats to and getting the button presses correct becomes frantic. The ability to use your own mp3s stored on a memory stick adds endless personalization and replay value. Available exclusively through the PlayStation Store website, this $6 download is easily worth the price and a definite must-buy.
