Hello. I've had this problem for a while now. With a few songs that I have downloaded, they just won't start, and if i skip ahead they won't play. I've tried reinstalling, logging in and out, undownloading and redownloading the song, etc. Nothing. They are tracks on spotify, but dont seem to work. I'm a premium member and would just like to be able to listen to these songs .-. I am on a samsung galaxy s5.
