It's so loud. If I turn down the music so the lobby music is of a normal level, then the in game music is way quiet. But if I keep the music at a level so I can hear the music in game, then the music is so crazy loud in the lobby and I can't hear anyone in teamspeak and it hurts my ears in the headphones. I know this isn't the first time this has been asked.
OR, a separate slider in the options menu for music in lobbies, as I know some like the loud burst of music and it gets some pumped up, however others do not like it so loud. This way people can tune the lobbies sound to their liking.
Lobby and ingame music have the same volume for me. The music during the title screen / Gamma disclaimer is always blaring at full volume, though.
