[WotLK] Music in Nagrand is broken

I was so hyped to relive some nostalgia on my Death Knight only to find out the music in Nagrand doesn’t work. No matter where you go it just keeps repeating the same orc drums over and over again, it started giving me a headache I couldn’t even quest there anymore…

Was this not reported in the Burning Crusade beta or live at all? How could this be bugged for an entire expansion?

This seems to be an issue in dungeons too, they’re all playing the same music track. Seems to be new.
