How do I cite a song lyric in a paper?

I had to write a paper yzing a song. Well, I got it back and apparently after you write out any line that's in the song, you need to cite it? How do you do that? The song is "Play Crack the Sky" by Brand New. So this would be my paragraph: There are a lot of examples of simile, blah blah "song line goes here" (WHAT GOES HERE?). Do I put in the song name, or the artist name? Ugh, I'd appreciate any help, thanks.
