Might just be a coupe of non-obvious settings, but I've noticed two things that puzzle me:
1. First situation is, I'm playing a long playlist and hit 'Pause' in the middle of a track. When I come back later and hit 'Play', it starts up where it left off, plays about a few seconds, then jumps to the start of the next track in the playlist. It's not consistent, in the sense that, if "later" is only a minute or two, it works as expected, finishing the track that was in progress. Typically "later" is several hours or the next day: this laptop is hooked to the living room stereo and pretty much dedicated to MB. And I don't know if it does it on my other machines, since I don't normally use them in this fashion.
2. Second, when it gets to the end of a playlist, it doesn't "rewind". I know there's a setting to repeat a playlist continuously, but I'd expect when it finishes the last track of a playlist and stops, I can hit 'Play' again and the playlist will restart at the beginning: at least that's how every other player I've used works. What happens is, it simply replays the last track again and stops.
It's running on Win10/64, whatever version was current when I installed it in February. Neither of these are deal-breakers, just annoyances.
