Did you lose your mind when Radiohead released In Rainbows with a variable pricing method? If you did and want to adopt this method for your own band, Smirp is a site that can help you. Smirp allows your fans to set any price they want to purchase your music, video or photos (though artists can set a minimum price). Once you receive payment, a link for downloading your record is sent to your fans via email. After 12 hours, the link dies which could lead to some really bad customer service hassles but helps prevent the download link from being spread around the net. They have two different pricing plans, a free plan where they take 20 percent of each your earnings and another with a few more features for a flat rate of $6 per month. At this point the sites layout is bare-bones, but holds a lot of promise for one of the many new models bands can take on.
