I am looking for software that would allow me to sync music and playlists across multiple devices: two computers (both running Windows 10) and a smartphone (running Android).
Ideally the solution would be network-based for synchronizing between the two computers, but I do not mind having to physically transfer the music to the smartphone. I need to be able to listen to music on my phone even when there is no Internet connection (e.g. when using the subway), so a purely network-based approach for it wouldn't work.
So far I've been putting my music in a file storage cloud service, and using MusicBee to manage playlists and synchronize with phone. This works fine for the music files themselves, but unfortunately not for the playlists: MusicBee uses absolute file names. This means that whenever I make a change to a playlist, I must manually do it on the other computer, which is not ideal and prone to error.
So far I have not been able to find music management software that behaves well with cloud storage and is able to sync with an Android device correctly. Does such a thing exist?
