I'm a passionate music enthusiast, buying about 5-10 releases a week, often rare stuff. While I really disaprove of using it as exclusive source of music, what.cd has always been my last-resort-source for music that would otherwise be lost or only available on 3-digit-priced vinyl. There were still a lot of gaps in the catalogue but it's probably the most complete collection of lossless music, organized in a way that is rare for user provided content online. A sublime experience.
