This usually disappears when you force close the Music app. If it’s still on your iPhone, double tap the Home Button to show the App Switcher, then slide the thumbnail towards the top of the screen (iPhone 8 and earlier).
Also, close all the tabs in Safari. If that doesn’t help, turn off your device and turn it on again.
I uninstalled the app and it was still showing up on the screen. I then went ahead and just deleted the darn thing. If I want my music I know where to find it.
