For anyone interested in finding a song but only know some of the words or only the tune of the song, you can download an app if you have a smartphone and sing some of the words or hum the melody. It will 8 out of 10 times find the song for you, especially if it's English. The app is free on the App Store and Htc store, I don't know with Samsung phones.
The name of the app is
SoundHound
Hope that helps
