[CLIENT] Lobby soundtrack continues to play after game starts

On seemingly random occurences, the soundtrack playing during lobby (e.g., howling winds in an ARAM lobby) stops playing during champ select, but resumes afterwards, playing during game loading and game itself.

I disabled Lobby/Post-game Music and Champion Select Music. Lobby music now randomly starts when I start the queue (then stops in Champ select and continues in loading/game). Cancelling queue and starting queue again usually stops the music during the new queueing. Most frequently however, the lobby music is properly disabled on first queueing.

Also, closing and restarting client during game stops the lobby soundtrack, but disables 'play again'.

This is a minor bug but it's especially distracting in ARAM, as the lobby sounds are louder. To my knowledge, it's been going on at least since 7.24.
