It seems to me that the majority of classical music that you try to find online (by title or composer) lists the composer as the “artist”. Or they list a compilation album without attributing the tracks to the performing artists, which are almost always orchestras. About 3/4 of my 500+ classical tracks have no performer information to be found. The only way AFAICT to get the info is to re-purchase the same music from orchestras I can identify, or to listen and compare mine track by track to identifiable songs, which would take more than my lifetime.
My first thought was that it had something to do with expired copyright, but that makes no sense, as it’s the old composers who have expired or non-existent ones. Yet, their names are almost always attached to the music – it’s the performers, who (in most cases, I would think) would have active copyrights and would be properly credited.
So… what’s the deal?
