I had this exact problem. I looked at what song it reached before it stops and then went into that song (or maybe the one after) on my library to discover that there was something corrupted in that song and wasn't displaying.

After I deleted and re-added it worked fine from then on. I believe that particular song was one of the first ones that I added annotations too, probably before the first update to fix a bug.

This might also work for you. Good luck!
