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.

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

Musicbee can pull your songs and playlists from itunes and allow syncing of them to your phone. It doesn’t do streaming though.

I had that issue as well with a USB hub that has charging. Turns out it was the hub that was the issue because it would throttle or even shut off the charging to other usb ports when there’s too high of a demand to prevent it from overheating. Swapped to a better usb hub and had no issues since.
