To find out what song is playing, you can use several popular music identification tools and apps:

• Shazam : One of the most popular apps for identifying music. It listens to the song playing around you and quickly tells you the title, artist, and lyrics. It works on both Android and iOS, can identify songs even when offline by saving audio for later recognition, and integrates with Siri

• Google Search / Google Assistant : On Android or iOS, you can open the Google app, tap the microphone, and say "What's this song?" or use the "Search a song" button to identify music playing nearby. You can also hum or sing a melody to Google, and its machine learning models will match it to the correct song even without perfect pitch or lyrics

• SoundHound : Another music recognition app that identifies songs playing around you. It also allows searching by lyrics and provides live lyrics for sing-along. It supports voice commands and integrates with music streaming services for playback and playlist creation

• Browser Extensions like Song Finder : If the music is playing in your browser, you can use extensions such as Song Finder, which can identify any song playing in a browser tab with one click, providing detailed song information

In summary, the easiest way to identify a song playing near you is to use apps like Shazam, Google Search (with humming feature), or SoundHound on your smartphone. For browser audio, Song Finder is a convenient option
