I tried exporting playlists form MusicBee today. Some of my music I had just copied from my computer over to my phone and that worked fine when I exported the playlists. However, a lot of my music was exported from MusicBee as it was extremely quick and didn't seem to have many problems (Outside of a troublesome time trying to pick the folder.)
But after moving over a playlist that contained music from about 4 albums I realized that the music that I had exported from MusicBee onto my phone didn't work with the playlists that were also exported using MusicBee, but the music I had copied manually worked just fine. I don't know if this is something about the way MusicBee exports or copies but it is quite annoying.
A fix or solution would be appreciated. If you need app information, I'm using blackplayer on my phone which is an android.
I used exported wrong, my bad. I used the "Send to" button to move albums onto my phone. I don't necessarily know if that means "syncing" it because I didn't fully sync it because I have a lot of music and only wanted to move over some of the albums.
By moving the albums "Manually" I mean I literally dragged the files from my computer into the phones files, rather than using the "send to" button.
Don't really know what you mean as "Copying these playlists as-is to a portable device is not going to work ever" as I have literally dragged and dropped the playlist files that I got by using the "send to" button in MusicBee, put them into my phone, and they worked. At least they worked with the files I didn't use the "send to" button to move to my phone using MusicBee and instead manually moved over by copying the files from my computer to my phone.
Maybe we're both not understanding each other here, it's definitely possible, as I'm not too great at getting my problems across as I find it a lot easier to screw around with it myself.
