Do you know that Shazam is owned by Apple?
As a result, Apple includes Shazam into iOS. It is therefore possible to ask Shazam for the details of a song that you hear directly through Siri: “Hey Siri, what is this song?” should be enough.
It is also possible to include Shazam in the control center if it is not already there.
To do this, go to settings, control center and click on the green “+” button to add it to existing controls.
To recognize a song, you just have to launch the control center and click the Shazam button and in no time the title and the performer will be displayed via notification. No need for the Shazam app except for more advanced features.
It works also on the Mac via Siri, obviously.
