Rhapsody allows search by composer. Search "Gustav Mahler" and you get all of the recordings of his work, regardless of the orchestra or if it's in a compilation with other composers. Looks like Google All Music does the same; no experience with Spotify, though. I share one of the higher-level commenter's concerns--the degradation of the sound quality. Being able to hear the valves on the instruments and the full range of music gives a much more immersive experience. I had a recording of Count Basie opening for Frank Sinatra (it's basically the hour before they recorded Sinatra at the Sands), and you can hear the audience's glasses like you were sitting in the venue. I love streaming for my DeadMau5 and background music as much as the next monkey, but I still buy the classical and jazz recordings on CD for those extra effects.
