I am definitely planning to go cross platform in the future and integrate other music streaming services such as Apple Music, however, the APIs that these other services offer are nowhere near as good as what Spotify offers unfortunately. Also when I first began creating this app around 3 years ago, and just prior to launching the Spotify hate wasn't nearly what it is today. My plan is to keep releasing updates and features for now until I'm at a point where I'm happy to start integrating other streaming services. Would be interested to hear your perspective on this idea.
