My Little Wu-Tang Clan- Shame on a Nigga
The Transformative Factor:
This video passes the Transformative Factor. It changed the meaning of My Little Pony, but not the actual song.
The Nature of the Copyrighted Work:
This video fails the Nature of the Copyrighted Work test. My little pony was already something published by someone, and it's also not nonfiction.
The Amount and Substantiality of the Portion Taken:
It fails the Substantiality of the Portion Taken test. It took a bunch of clips from episodes of My Little Pony and the entire song.
The Effect of the Use on the Potential Market:
I think it passes the Effect of the Use on the Potential Market test. Little kids are the target for the show My Little Pony, and I really don't think they'll be watching this on YouTube.
Overall, I think My Little Wu-Tang Clan- Shame on a Nigga fails to be fair use. It failed the Nature of the Copyrighted Work because its not nonfiction, and someone made it up on it's own. It also fails the Substantiality test because they took a lot of clips from My Little Pony, and also the entire Wu-Tang Clan song.
