Let your iPhone tell you what song is playing : Shazam
So you hear a really catchy, unfamiliar song in the club and you have no idea what it’s called. You hum it to yourself repeatedly in an attempt to memorize the lyrics, only to forget it after slamming a few shots at the bar. Shazam will never leave you struggling to recall those lyrics again. All you need to do is to hold your iPhone close to a speaker playing the unknown tune and the app will identify it — album, artist and song title — just like that.!!!!
You can even play it again for free on Youtube for iPhone and of course, download it from iTunes.
