Breathe guys. Breathe. The all caps and panic over something that hasn't even happened yet. Maybe the workers were sick of hearing bongos for the last several weeks. They're playing a lot of music- maybe they're testing the track for a grad bash or a paid event in the fall, etc.
Between all the Universal parks, there are multiple soundtracks. I'm going to go out on a limb and guess that we'll get the tropical music that we've been hearing for the past month vs the beachboys we've heard just this morning for the first time ever.
This is as premature as "omg the water isn't colored", then the next day the water is colored.
Man, you some of you guys seriously overreact to the smallest things.
