Seriously, apart from the first few seconds of the title theme that is blasted into your ears every time you log in. The rest is simply forgettable, uninspiring and samey.
Though there is only one track played in Guild Wars 2 that is legitimately not forgettable to me.http://www.youtube.com/watch?v=yxa7n1mXVMs
Guess what. It's a Guild Wars track that hasn't been altered in any way that is played in Guild Wars 2. This track was memorable in Guild Wars 1 and it is still memorable in Guild Wars 2. This track is creative and beautiful. The new tracks in Guild Wars 2 lack such a soothing and atmospheric melody this track has. If it wasn't for this one track, I would have muted Guild Wars 2 music a long time ago.
