Hi. I've been using MusicBee as a music library manager for a couple of years. Of course, being a desktop program, it doesn't keep playing when the machine's cover closes. This is, literally, the only thing Groove Music is good for (I swear, I think my original Rio MP3 player was more versatile than Groove Music). Is there a better player that will keep playing when the SP3 cover is closed? I don't really mind managing the library with MusicBee, but isn't there something in between, something better than Groove?
