Today I tried to record an video when my son dancing but when I presses record, the music ob my phone won't play. Tried several time and nothing change. Getting annoyed. What can I do ?

I'm afraid you can't.

Even using PIP it stops when taking a video.

Just to add, there's nothing wrong with your phone nor the camera nor the music app, its working as intended
