What's a good way to manage music where there's not a simple/tidy name for the performer? Are there tools that are good enough at handling metadata, that the structure of the audio files on disk doesn't matter so much? Before, I've organised things like `~/Music/Artist Name/Some Album/A Song.mp3`, and just used the media player of the day. But, that doesn't work great to find stuff by a particular musician when they tend to get together with different sets of other musicians to record one or two songs in any particular arrangement.
