I used to use MusicBee extensively, but stopped a couple of years ago. I just came back to it and it was not helpful in setting playlists and using my music.
It just got FAR too complicated.
I would like to be able to make a playlist from my songs without having to read a manual, watch videos, and read a user help forum. It is not a tough task.
However, with several thousand songs in my library, I can't easily find any of them through the interface. It is far easier to browse through Microsoft's file system to find them. Yeah, it's that bad. With MusicBee, I get ~8 different categories that have Weird Al songs. All show up as Weird Al, but they are not combined. Nor are they sequential. Again, just going into the file system is easier to browse to a particular song.
The software is acting like it is designed for the hyper-invovled, not the casual user. If that is your target market, then great. But, I'm not that user and will never be.
Writing this is about the limit of what I want to contribute to use a simple app like a playlist manager. Before completely trashing my (limited) contribution, ask yourself why a well designed app for managing music needs to be complicated for everyone (it's OK if there is complexity, but it should start with simplicity).
