Apparently Lady Gaga is the only one allowed to make pop derivatives. The Daily What summarizes the spat between her and Weird Al Yankovic, a sort of pop music version of Trump vs Palin:

[He] wanted to include a spoof of Lady Gaga’s “Born This Way” in his upcoming album — with all proceeds from the sale of the song and its subsequent music video going to benefit the Human Rights Campaign — but her management told him Ms. Germanotta would need to hear it first before final approval.

He sent her the lyrics, but was told she would need to hear an actual song. So Weird Al went to work producing a finished product for Lady Gaga to listen to. “Now, I never do that – never,” he writes in a blog post, “[b]ut because I was really excited about this parody, I decided I would faithfully jump through as many hoops as Gaga deemed necessary.” He cut his family vacation short and spent day and night in the studio in order to deliver the mixed and mastered track in a timely fashion to Gaga’s people.

A few days later he finally heard back: The answer was no.

So Weird Al released it on YouTube instead. Shortly thereafter, he got the go-ahead from Gaga:

Apparently the fact that she didn’t approve it was news to Lady Gaga herself! Gaga’s manager has now admitted that he never forwarded my parody to Gaga – she had no idea at all. Even though we assumed that Gaga herself was the one making the decision (because, well, that’s what we were TOLD), he apparently made the decision completely on his own. He’s sorry. And Gaga loves the song.
