It's useful to set this app as default for opening audio files. However, the app doesn't support this.

Describe the solution you'd like
It would be nice if I could open any music file with Gramophone, just like Auxio does.

Describe alternatives you've considered
Auxio

Additional context

Thanks, but wouldn't it be better to open it in the app itself, instead of playing the audio as a popup?

When I minimize the file manager, the audio stops playing. I'm sure that's not what most people want.

Thank you for your efforts BTW
