strange music plays while in App Store

for a short yet undetermined amount of time lately, i’ve been having music play while i browse the app store.

it’s not just an app playing(or at least i can’t find out how to stop it) because i have allowed the sound to play for some of the demo videos and the music plays along with the trailer/demos.

i have attached a video capture of what happens and will upload that along with this post.

please help me figure this out, it’s incredibly annoying.

also sorry if this is posted in the wrong place. there are categories and “iOS” and “App Store” were not options. the post would not post otherwise.
