What sucks about Discogs
Is that it can't decide whether to be for the pros or to be a fun thing for fans to track their music collection. Many albums have a zillion entries in the database, representing each issue or version of a given release; they can differ by as little as a particular pressing plant. If you're a pro you'll know which listing to use; if you're just looking to buy a record or to list your own there's an overabundance of listings (that can make a simple transaction more complicated.)
Hell of a place to get classical-vinyl cover art though.
