Tangent, and this may be one of those cases where I learned about this on HN and am now passing it back to HN so pardon if I'm just late to the party, but if you're a regular Shazam user on iPhone you don't need to open the app anymore. You can just add a widget to control center. https://support.apple.com/en-us/HT210331
No, it definitely is not. Besides on many occasions I would not even want to do that.
Fastest is simply turning on “Shazam on app start” in the settings and then starting the apps. However if your phone is locked then indeed what parent commenter said is quickest.
