what.cd was the world's greatest music discovery mechanism. You could always ask for recommendations in the forums or in the comment thread of the albums pages. The community always delivered. I miss that type of camaraderie. I also spent more on music as a member of that community than since it has been disbanded.
OiNK before that, too. Once waffles and what disappeared then I was never 'able' to get on to one of the newer ones… the whole process is some real archaic thing. Used to have a great 'profile' on those others, but yeah.
What.cd was the Library of Alexandria for recorded music, the depth of what was collated and properly labelled there was far beyond anything that has ever existed on any other service, paid for or not. Every permutation of every release, endless live recordings, often multiple of the same event, absolutely incredible.
