I've used Prime music for YEARS, yet SOMEHOW on Android OS, it don't download My playlists correctly from the server, takes WAY too long to recognize inputs, all the sudden has a max playlist size of 2,500 (even though My playlists are well over that #, which causes an error fault/message when I try to edit them!), AND the menu options for add to playlist/My music is GONE, & so is offline mode, just spent 17hrs trying to setup this BS on My new cellphone, only to find it won't work offline. FU!
