How do you find a song if you only know some of the lyrics? Recently I saw a commercial for an XBox game and there was a song in it I liked. A very melancholy song, but it had a good beat. I could only grab "worn out places from the song during the commercial. 

If you jump onto Google and search for the partial song lyrics inside quotes followed by lyrics, you can see the song you're looking for. 

Here is an example search for the song lyric I was looking for.

This is a great timesaver.
