example: someone asks the band squeeze to do a commercial using one
of their songs. squeeze refuses. the ad company then hires people
to replicate the sound of squeeze perfectly, and write a song
intentionally meant to sound like the song squeeze refused to give
permission for. same key, tempo, phrasing - but it's not the same
notes or chords or words. even though this practice is done to
intentionally fool the public into thinking it is squeeze, or at
least associate the squeeze sound with a particular product, that is
perfectly legal, even though it has no artistic merit and is recorded
strictly for commercial use to generate a profit.
