A. 1. Check if the app has any settings related to background listening. Go to Settings > Shazam and look for any options that may enable background listening. 2. As a workaround, you can keep the app open and your screen on while listening to music, but this may drain your battery faster.

B. 1. Use the 'Shazam' widget on your home screen for quick access to the app, allowing you to quickly identify songs without having to open the app each time.
