If you've ever heard a song and gotten frustrated trying to remember the name of it or who performed it, Shazam just may make your life easier. Essentially, it's an audio search engine. Available for iPhone or Android, the app can listen to virtually any track for a few seconds, compare it to a database and almost instantly come back with information about the song.
Shazam goes beyond just satisfying your curiosity. You can buy the song that you're hearing and share it with friends, all with the click of a button. Shazam will also download the lyrics for the song you're hearing, and it enables you to tag songs so that you can recall them by key words. It also connects with Pandora, letting you listen to the song you've identified, then go on to hear a mix of similar tunes.
