Would you like these push notifications on your Android smartphone disable, then you can this very simple off in the app itself. Opens to the Home Screen from the menu and then the app "Shazam". Typed within the app at the top right, the symbol with the three points. In the pop-up window select "Settings".
So you see all Shazam settings. Under the section "General Settings" menu item is stored "Notifications". Removes here the hook in the checkbox to disable notifications on the lock screen and status bar of your smartphones.
That was about it.
Immediately you will receive on your Android Smartphone no more Notifications by the Music app Shazam.
