Sony's giving users a chance to perform a remix of the classic "Subterranean Homesick Blues" by Bob Dylan, and whoever does the best job of re-creating the song wins a trip to South by Southwest in Austin in March.

Each of Dylan's recorded tracks are separated for your mixing pleasure. Individual Dylan vocals, drums, electric guitar and bass lines, along with dozens of other tracks performed by various artists, can all be mixed together for a unique result.

This is tons of fun. Once you get the hang of it, it feels like you're actually creating a new piece of music.

The Remix Project Flash app allows more talented users to record their own musical tracks to add to the mix. It gets really interesting when you take a look at the remixes people have already created — these are sorted on the site using a filter for most recent or most watched, along with an offer to search for a username.

A panel of Sony judges will decide which remixes are the best, and the company will announce the top 10 remixes on January 24 via its Facebook Page. Visitors to Sony's Facebook Page will also be invited to vote for their favorites.

This is a brilliant piece of viral marketing from Sony, shining the light on the brand without forcing the issue. It's not surprising, given Sony's history of creating fun apps and games to call attention to its brand. For example, look at the company's spy-themed Facebook app from last May.
