One of the great tragedies of Tower Records' lingering demise was that classical music lovers lost perhaps their most reliable source of recordings. Say what you will about brick-and-mortar record stores, there was something wonderful about finding what you wanted where it was supposed to be. Just try looking up, say, Bruckner's Fourth Symphony on Amazon and see what you get. (Amazon's AI, as good as it is, is a classical music idiot.)
