www.legalsounds.com works out to 9cents a track (around 75p an album) you pay up front ,I have been using it since xmas (around 700 tracks)and have got a few friends on it with no problems. easy to use and great library , it keeps all your purchases so if you loose any, you can download again free. if you default your itunes then it more or less puts it on itunes automatically. tell your friends by a link and it credits your account for about 4 albums.well worth a try
