I've only recently started using MusicBee. Most of the program works well, but I've found that performing a simple task such as removing the rating from multiple files at once can cause the program to stall for long periods of time or straight up crash. It seems proportional to the amount of files you attempt to edit (editing 2000 files will cause more problems than editing 20). Although I understand that this is normal, the delays are significantly worse than what I would typically experience in iTunes, which I used previously.
