Shazam is an app that identifies songs by listening to it for a short 10 seconds. It is one of the apps I use most often, as I am a big fan of all music, and I am always curious to discover new songs that I like. How Shazam works is through “audio-fingerprint”, a concept that is too technical for me to understand, but the app itself is designed well and its functionality is absolutely amazing that I use this app almost everyday. It is even connected to Spotify, so that you can listen to the entire songs and save them in your playlist.
