Some songs not playing

[ckbrulez]

My Question or Issue

I have an iPhone 6S which works fine. Spotify is updated and works almost perfectly. I will open it up and play my music which works great, but some songs in particular just wont play. I will be going through my playlist like normal and then a song such as 100 Bad Days (AJR) will come on and just not play. The progrees bar will be stuck at 0:00 when this happens. It also happens with a few other songs as well. I know the problem is not my volume. Any suggestions?
