My main issue with the non-looping open world music is when I am gathering that silence is painful. I can understand it if you were just going from Point A to Point B for a quest then moving on to another area. But with gathering you're there for an extended period of time usually, so the music is eventually gone and all you hear is the clanks of the tools repeatedly. That ambiance is now gone since I hear nothing but clanks, defeating the purpose.
