NOTE: For works with no page numbers, such as sound recordings, it is preferable to include the creator's name in the text and omit a parenthetical reference altogether.
The person cited first (e.g. composer, conductor, performer) in a works cited entry for a sound recording depends on the desired emphasis. See the MLA Handbook (5.7.2).
If a recording was obtained online, include a link to the website at the end of the citation.
