Has gotten better with time, I thought the most recent update broke YouTube music. Since recently it now fails to play the next song and sometimes goes 1 second over or just sits like it's loading even with good service. The issue does seem to disappate with wifi usage, but I'm thinking it's some type of server issue now. I downloaded an old version of YouTube music from January and it seems to be still doing the same thing. Too many people complaining about the same exact issues though.
