803.6 (B) (2) Remix
A remix is a recombination and manipulation of audio tracks or channels from a preexisting sound recording to produce a new or modified sound recording. Remixing from multi-track sources generally is a sufficient basis for a copyright claim in a derivative sound recording. Likewise, if a producer and/or engineer is able to manipulate a number of variables and make creative judgments or decisions in determining the outcome of the new recording, there is usually a sufficient basis for a copyright claim. However, the registration specialist will communicate with the applicant to clarify a claim in a remix from monaural or stereophonic sources, because in such cases it is unlikely that there was sufficient derivative authorship. In all cases, the remixing of preexisting sound recordings must be lawful to be copyrightable (i.e., authorized or permissible by law). 17 U.S.C. § 103 (A).
