This should be free. It really is an album sampler. It's a 15 minute track of each of the songs flowing into each other. They're not even full versions. If you want to sell well, release your samplers for free like with those cds at the concert, don't make people have to pay for previews.
Also what lazy asses! The image they used is a stock image.
