Doesn't stop playing music on quit – Stezza: Simple Music Player Review

This is as simple as implementing an application will terminate callback, but the developers haven't done that. It's obnoxious to quit the app, but still have music playing. EDIT: Developer responded by saying this is by design and music is "supposed to continue playing while app is not in the foreground". This is not a question of foreground and background states, but one of terminated states. Spotify, Apple Music Soundcloud, Youtube, etc. all stop playing when the application quits. It's obnoxious to require some ulterior method to stop the music when you quit an app. This is not a feature, it's a design flaw.
