JessDL I have no plans to as I want to keep this as a player for your local music. In addition I think the data structure for the content of this app & Spotify are different so it’ll probably be difficult to integrate.
Also there’s probably some Spotify developer terms that prevents this. From my brief look, I see:
“Do not build products or services that mimic, or replicate or attempt to replace a core user experience of Spotify or its group companies without our prior written permission. Your product or service must add independent value or functionality that improves users’ interactions with Spotify.”
Which is probably what you’re asking for?
