A mashup or blend (also mash up and mash-up) is a song
or composition created by blending two or more pre-recorded
songs, usually by overlaying the vocal track of one song
seamlessly over the instrumental track of another. To the
extent that such works are 'transformative' of original content,
they may find protection from copyright claims under the "fair
use" doctrine of copyright law.
