I first want to say that I absolutely love the music in Guild Wars 2. Every track is amazing and it really adds to the game as a whole.
One feature I would really appreciate is a chat command to view the name (and possibly other info) of the current music that is playing.
Typing /currenttrack into chat could bring something back like “Track 06 OST, Trackname” as yellow text in the chat window. I would really love to listen to this music outside of the game, but sometimes it can be daunting searching around for “that music that plays in this area” or “the music from this quest”.
