I've cancelled mine. For unknown reasons, songs continually get randomly deleted from my device and playlists. And not just once. Several times now I have spent time building playlists with Apple Music and downloading them for offline viewing. Works great, until... Boom, half of them are gone for no reason and the only way to get them back is go find them again... if you can remember everything you had put in the list. How hard can it be to save and keep songs in a playlist? Apparently too difficult for Apple Music.
