Not playing full playlist

[tv006]

I've noticed since I listen to music overnight that the app hasn't been playing my entire playlist. If I use shuffle it seems to only take a certain number of songs, shuffle them once and then if repeat isn't on it stops playing after however many songs play but if its on it will repeat the songs in the same exact order as the first play through. What is the point of a playlist if it won't even play the whole thing? Playlist radio may even be doing it too.
