We heard your feedback, and have temporarily added the ability to toggle between the Bilgewater Music and SRU music.
You can find this option under the in-game Sound menu, near the bottom.
**Your audio will default to Updated SRU music, so if you want Bilgewater music, you will need to toggle it.**
We are looking into the amount of effort to get this fix live during the Bilgewater Event, so that players who want to opt-out of the Bilgewater music can. :)
Soon after the event is over, we will rotate the Classic music option back in.
Thanks! If you have any feedback, or bug reports, feel free to shoot 'em my way!
