Sony and Bob Dylan have launched a remix project (called "make.believe") that gives you a simple sequencer and a four-track separation (vocals, guitar, drum and bass) from which to produce your own mix of the classic "Subterranean Homesick Blues" (you can also mix in your own recordings). Your mixes are shared on the Sony Music site, and compete for various prizes (including a trip to SXSW in Austin).
