Modern music players and online stores are really neglectful of classical music. I downloaded an album of Jascha Heifetz recordings from the Google Play store, and the track titles are all of the form "Violin Concerto in D Major", "Violin Concerto no. 2", etc, with no indication at all of who composed which piece. The tagging is terribly inconsistent, with the artist sometimes being the composer, sometimes the orchestra, sometimes the conductor, sometimes the soloist, sometimes an arbitrary subset of all those.

I'd really like for someone to make a music player or online store that worked better with classical music. Hell, I'd settle for one that didn't suck.

Have you tried arkivmusic.com? They're classical music only, and a pretty good place to get music. I buy physical CDs only (the crappy tagging being one of the reasons), but they seem to take classical music seriously, so my guess is their digital downloads would be pretty good regarding tags and other info.

Hey! They also have Baroque and Renaissance music, not just classical!

Tag your music with musicbrainz.org, they have very strict guidelines for tagging, and when they don't have a release you have bought, you can research and add the information yourself.
