So I go to my favourite tracks and select the first track, I have it off shuffle, and am expecting it to play through my music but it won't. If I select a random track further down my list then press skip, it goes back a track not forward a track. 

My app is up to date.

I get a lot of other issues, like the music just stops randomly. A lot.

I dont know exactly what I'm paying for tbh as I'm not getting much of a service. I only want to play my music.
