The songs are usually credited on Imdb.

I put “Shazam” into https://alternativeto.net and selected the “open source” filter. Not sure how good they are.
If you’re watching the movie, or just have ambient music around.
ListenBrainz (The Official ListenBrainz App) https://f-droid.org/packages/org.listenbrainz.android/
Hopefully you know of F-Droid.
Maybe Ambient Music Mod (Port of Now Playing from Pixels to other Android devices) https://f-droid.org/packages/com.kieronquinn.app.ambientmusicmod/ is of interest. I’m on a Pixel so not helpful to me.
