Not necessarily.... The Posterchild for parody is 2 Live Crew Pretty Woman. Which includes samples of the original Oh, Pretty Woman. Youtube videos get flagged for 10 seconds of a song snippet all the time.

After the Campbell v Acuff-Rose Supreme Court decision, 2 Live Crew licensed the song from Acuff-Rose music. (which is what they tried to do in the first place).

I'm guessing the next Weird Al has already been disillusioned with the copyright ban hammer.

Didn’t even need the next Weird Al. Al’s own YouTube videos were copyright claimed by his own label for violating copyright.

Weird Al himself was well aware of this issue, and famously would only parody songs after receiving permission from the authors.

Permission from the authors is unfortunately different from permission by the copyright holders. IIRC Weird Al did it more for goodwill than legality.

> Al does get permission from the original writers of the songs that he parodies. While the law supports his ability to parody without permission, he feels it’s important to maintain the relationships that he’s built with artists and writers over the years. Plus, Al wants to make sure that he gets his songwriter credit (as writer of new lyrics) as well as his rightful share of the royalties.

Parody is a fair use defense, so you have to go through a lawsuit to be able to assert it.
