Bum Rush the Charts is a grassroots effort by bloggers and podcasters to demonstrate the power of independent media by sending one track by an independent artist to the top of the iTunes Music list for a single day (or longer, if possible).
The bum rush begins March 22 at midnight as everyone involved with the effort buys the track "Mine Again" by the band Black Lab. If you buy the track via an iTunes affiliate link on the Bum Rush web site, the organizers will get a cut of the funds, which they're then putting into a college scholarship.
I think this is a great experiment for a number of reasons. For one, podcasts have grown tremendously over the last two years and while traditional broadcasts have a far greater listenership, I think podcasts can have an influence that far outstrips the size of their audience. This would be the first tangible test of the power that I've seen.
Second, a lot of people have spent a tremendous amount of time complaining about the music industry; this gives them a chance to do something positive about it, to demonstrate that yes, an alternative really does exist to the status quo.
