Guild Wars 2

Hello everyone!

I’ve been wanting to do some Guild Wars 2 Videos on Youtube.
But I do wonder about the legal issues I could come across. Is it allowed to use the Guild Wars 2 and/or Guild Wars 1 music in a GW2 video? Either being the real background music or use it from my CD/digital track from iTunes?
Help is much appreciated!
/edit
Forgot to mention for a non commercial use only. I don’t want to earn money with these videos I want to make.

I think you can better ask this in the account issues-section. though that isnt the right forum either. the arenanet people walking around there know a lot bout the rules they put up over their intelectual property. As far as I know they allow it as long as you don’t claim to be the owner of any music nor footage taken in the game. Im not sure if this is the same for the official music (official music taped ingame is ok).
