You can quote the lyrics of the musical record (song) and quote the name of the song, artist, recording studio, etc. Here is the format that is required by MLA handbook - 7th edition. Musical Video Artist or Group name. "Title of Song." Title of Album. Music Video. Label, Year. Backstreet Boys. "I want it that way." Millenium. Music Video. Jive, 2000.
