JamGlue

Providing "remixes for the masses", Jam's a free engine which lets you easily and creatively craft your own beats or hack up existing songs to add a serious personal touch. The simplest way to figuring out functionality is by listening to a 3-minute tutorial, which will lead you through adding tracks and finding/uploading effects from your own files or from Jam's extensive library (loaded with drums, bombs, lasers, and movie sound bites. Once you get those down, you can get creative by adding as many layers as you want to your mix, such as fading to the left or right channel, as well as speeding up/slowing down and altering volumes on each track. If you're feeling good about your skills, you can enter all different sorts of prize-dishing remix contests, where you'll put your work head-to-head against other people's tweaking songs from artists like J.R Writer, T-Pain, and Public Enemy.
