There seems to be a lot of tag abuse in their catalog for exposure, although I'm not sure if artists are assigning their own tags or if it's done by an algorithm. I'm trying to find "classical" music and I'm getting a lot of electronic/jazzy stuff. Try to search for "flute" instruments and I couldn't find one track on the first page of results that had a flute in it.
