Filming, recording audio and playback to Bluetooth earbuds for drumming

Hi,

I'm having drumlessons and I want to record myself to listen to how I play.

I have music files on my phone which I playback through my earbuds which I have in my ears while drumming
Filming is done by my Samsung Galaxy S10+ via the normal camera video capabilities.

What I want to achieve: I would like to film myself, hear the music in my earbuds to play along, and also record these same music in the video.
This way I can play the video to hear me drumming along with the song.

What is the best way to do this, or is there a special app which achieves this?

Currently I film, play the music and select the screen recording option, but that is a lot of work. By the time I switches screens, the music has already started but I was not able to play along yet hahaha.

Is there any app that records video, and also the audio that is playing through bluetooth?

Thanks.
