You can already make this change on your own. In fact you can change it to any song or playlist you want. Instructions can be found on the gw2 wiki:https://wiki.guildwars2.com/wiki/Customized_soundtrack Me personally, I would like to see an update/change to the login screen, but I do not see that happening until the Expansion is released. In the meantime, I have changed the login music to my own playlist of the original GW2 Overture, the GW1 Overture, and the GW1: Factions Overture. Oh, the memories.
