Is there a fix for the music playing during loading and game?

I'm sure it's been reported, but is there anything that can be done?

It's only started happening to me the last week or so. The lobby music will play when I've entered the loading screen and into the game. Closing the client is a "fix" but annoying every time I have to do it.

I've turned off lobby music to see if that helps but just did it so don't know if it's a solution.

Thanks!
