Buried in the official comments from Turbine on the Facebook status for last night's unexpected issue with the login servers is this gem:

"The Lord of the Rings Online Andy, we are aware of the music issue. We had a test earlier today for a potential fix for Update 11.1"

It will be interesting to see if Bullroarer is up around the 15th for 11.1 as predicted originally, and what if anything else of consequence winds up in the patch.
