When I play music from library (playlists, album etc.) the music stops playing after a song or two.

I am using Chrome with Windows PC and Android app (both with Chromecast), but it happens both places. This is a new problem when playing music from my library.
I had a problem with playlists before the latest development. After playing a certain number of songs on random the playlist stopped playing. Sorry if these problems have been adressed before, but I can’t seem to find any answers.
