Q-Games' next PixelJunk project isn't really a game. Instead, it's a music appreciation app that utilizes the PlayStation Move.

Originally called PixelJunk lifelike, PixelJunk 4am finally has a release date: May 15th. The app will be available in two flavors: a full release, and a free viewer that allows you to watch--but not create--live performances.

If you just like to listen and watch, 4am also functions as a standalone music visualizer for music stored on your PS3's hard drive. "You won't even need a Move if you just want to fire up and run a playlist to the visuals," the PlayStation.Blog notes. While you won't need to play to enjoy the app, you'll need to if you want to unlock some of the "rarer visualizers."

So how does one play 4am? Using the Move, you'll be able to select samples and apply effects. "Each song has 4 track instruments you can use: a Drum, Bass, Rhythm and Synth. Each track then has 4 different looping samples and four one-shot sounds in space around you that you can use. All of the loops and samples are different for each song as well, meaning events can have up to (4 loops + 4 one-shots) x 4 tracks x 5 songs = 160 different sound samples to pull from and mix however you like."

Confused? 4am is clearly designed for experimentation. However, if you want to get an early trial of the game, you'll want to jump in on the beta. Early access will be given to PlayStation Plus members who own a Move. There will also be a free Viewer beta available to all PlayStation Plus members. "During the course of the Live Beta, we'll host some special live performances from around the world, including DJ Baiyon performing live from Japan," the blog promises.

The beta begins on May 1st, and runs until the final release of the "game."
