Pandora was worthless, though, because of their skip limit (even in the paid version). Even with its effectiveness, it would still feed me junk.
This guy is a classical music guy, though, and all the pickers suck, for that. Classical has been treated badly, forever. I am extremely disappointed that Apple segregated classical into its own app, because I have always enjoyed mixing it in with my regular music.
One thing about classical music, is that every performance is a “cover.” Who performs the piece is just as important as who wrote it. None of the selection services seem to understand that.
MP3 tags are pretty much worthless. They are incredibly limited, and I don’t know why they have never been improved.
