Help avoid one music app stopping play in another app

[dino saur]

I would like to know ic it is possible that when one music app is playing a song and you start playing a song in another app, then the first play is not stopped, and both apps keep playing music dimultanously), the same way it works on a pc. E.g. Spotify, Deezer, music player etc.
maybe a script can do the trick

You could try a dj app and see if it will play two tunes at once
