Interesting sound glitch

Happened to me on accident, did it again and managed to recreate it.

Walk to a town (could be anywhere I guess I was on my way to lumby) and find the ground tile that switches the music to the music for that town. Turn all the sound options off. Log out.

Log back in. Don't move, and then do something that will trigger a random. What I did was high alch yew longs for about a minute until I got the pinball random.

Before moving, turn the sound options back on. It should be playing the music from where you logged out the first time.. for me it was lumby music. It will stay that way until you finish the random.

Weird eh?
