"We are not evil" is the slogan of music download service and record label Magnatune. Using the shareware model, you can download an entire album in 128kbps MP3 as a way to "demo" it before you buy.
Then if you want to buy, you get to choose the price you want to pay between $5 and $18. Seriously, you select how much you want to pay. If you give them $18 for an album, you get a heartwarming "we love you" message. Then you receive the album either in FLAC, MP3, AAC, WAV or regular old silver discs in the mail.
The noble premise of Magnatune is to send more money back to the artists, aprox 10-20 times more money than they get from the big dogs. Interesting idea with a flawless site, check them out for all kinds of interesting tunes in many different genres.
