[Feature]: background music mode

[nanderer]

Description

I like to listen to audiobooks, also to have some instrumental music with it, but on android you normally have the audio focus behaviour which prevents multiple apps playing at the same time. I am able to work around it using mpv from within the termux app but it would be nice to use rimusic which would save me the work of downloading albums and creating shell scripts

Suggested Solution

Two things would be necessary :

First an android independent volume mixer (this is also usable in case of imprecise Bluetooth volume controls) that allowes you to decrease the volume within the app before it hits the android sound system, spottube dose this very nicely

An option to dont send and receive audio focus events so it dose not stop and is not stopped by other apps playing audio

Optional things would be:

You could also add a sync play pause state option and an option to pause resume on headset connect/disconnect

Also nice would be a way to have multiple open playback queues open to switch between, so i can have maybe a rock queue to listen to with others, one for myself and one for background music so you can easily switch between them, right now i am using multiple apps for that but it would be noce to have it all in one..
