Delete songs glitched or unavailable - email saving
3 stars because there isn't a way to delete songs out of a playlist, simply using the add songs button and un-selecting the song doesn't work and there isn't a feature to delete songs from a playlist at all. Also 3 stars because if someone were to replace their phone, if they do not download the songs then all of the songs saved would be lost without an email tie in. You have the option to tie your email to your account on music player, so that if you lost your phone and got another one you could log in and all of your undownloaded songs would still be there.
