How do you cite a song in an MLA paper?

I want to cite the song, "Dirty Harry" by the Gorillaz in my research paper on them, but im not quite sure how to cite the musical source, WITHIN THE PARAGRAPH. For instance, to cite a book, you'd put (Author's name, page #). I'm at a loss an this is due friday. Please help, I'd really appriciate it ^__^
