Did you make this site? If I were the creator, I would not show it to strangers until I seeded it personally with 100 or so tracks. Nobody likes an empty party.<p>EDIT: typo: "current for forever" => "current form forever"
You might have a hard time getting orchestras to donate their work. Who knows, though.<p>At any rate, once the recordings from the 1950s go into public domain, almost the whole body of classical work will be available.
