Need ideas of solving problem with app I built

I built this app: https://play.google.com/store/apps/details?id=com.FindNewMusic_Vakil

But ios keeps rejecting me for following reason:

Guideline 4.2.3 - Design - Minimum Functionality


We were required to install Spotify before we could use your app. Apps should be able to run on launch, without requiring additional apps to be installed.

Next Steps

To resolve this issue, please revise your app to ensure that users can use it upon launch. If your app requires authentication before use, please use methods that can authenticate users from within your app.

Even though I added another functionality which enables you to view artist in app (following pics). Any ideas of what I should do to get app to be approved because I am lost at this point
