Voice recording while playing music

I switched to android a few years back and recently switched back to Apple when I got my iPhone X. I used to be able to play a song off of Spotify or Apple Music and record using the mic using the default voice recording app or another app from the App Store. I use this method to practice guitar and sing to backing tracks while recording to get feedback for myself. This method doesn't seem to work anymore, as all other audio cuts out when the mic is on to record. If I'm connected to my car's bluetooth I notice that my car detects recording like I'm making a phone call, making me think that their mic is unable to be used overlapping with other apps.

I was pretty excited to switch back but this is a big issue for me, does anyone know of a solution?
