I had trouble getting Sonos to see my iTunes playlist. I thought it would be easier to go native, and use Sonos playlists instead. I have noticed two things, but may be mistaken; 1) there doesn't seem to be a way to download / backup the playlists and 2) there doesn't seem to be a way to remove songs from the playlists once they've been put there. Am I wrong? If not, I'm thinking of another application to manage my playlist. I'm worried that, with the eventual disappearance of iTunes, that the application will no longer be supported. Can anybody recommend another third-party playlist management application?
