Sure a lot has happened to them that sometimes go for a place or have the radio on and listen to a song they like but do not have the faintest idea what it's called. For such situations there is a great app called TrackID that can be used from our Android device.
TrackID "hear" the song and then look in a database. While similar applications are already available, it never hurts to try a new one.
TrackID can be downloaded free from Google Play.
