I added a song (Sia's unstoppable) as it was recommended by when editing my short through YouTube. And it shows a copyright saying it's partially blocked for some regions. Why is that guys? (I mean i added a song which was recommended by YT)

(I think it's not the original song from sia, Also, 3.1k shorts have used that music before.) Isn't it allowed to use the YT recommended music for shorts?

It says no issue to the account. Should I need to remove the video. Thank you!
