It adds it to local folders so you can pretty much use any music player app you want. I like personally like poweramp. I just add the directory with my playlists which are .m3u and it they just pop up
The problem for me is that my music is arranged around "smart playlists". My music library would be unmanageable if I had to add every song to playlists manually.
Ah, then musicbee might not be for you. I've managed my own songs for at least a decade the old fashioned way so it was easy to import and move my songs around to other forms of media apps. You can however copy and paste the Playlist from iTunes to musicbee. You don't have to manually add all the songs to the playlist from your library.
Hmm, okay maybe I will experiment with it. It seems I read somewhere that there was an issue with doing this. Have you tried it? Then whenever I add new music I'd have to remember to add it to this playlist. Other playlists would automatically use the local copy?
I have Plexamp on my phone configured to automatically download the "loved" album (songs I've rated 4 or 5 stars). It automatically downloads songs I add to the playlist. My library is too big to download it all to my phone (most songs are in FLAC format) so I'd need to download a curated list anyways.
This seems to work well. I've used it a few times on flights or when I'm in a hotel room with spotty phone coverage and no wifi.
