I am unable to listen to songs without Internet (even tho I have premium). My Spotify glitches when I want to do group sessions. When I want to rewind or fast forward a track it just continues the play through as usual. The only benefit is I can listen to songs in any order but of I'm giving up £6 a month (thats WITH student discount) and I'm not getting the quality of service I asked for then I'll probably switch to amazon music instead.
