Updated 4/24/16: In the wake of Prince's passing, you should really check out this awesome, shiver-inducing performance. Yeah, Prince was weird for trying to keep this offline, but he could be weird like that. He also refused to let Weird Al cover his music (which, technically, Weird Al needs no permission for), but nobody's perfect. This is still an awesome video.
12/8/16: Way back in 2008, Prince covered Radiohead's sexual weirdo hit "Creep" at Coachella, then click-blocked YouTube and anyone else trying to host it by claiming copyright infringement. This is a lot of baloney, because it's not his song! There are quotes from Radiohead frontman Thom Yorke from as far back as when it began in 2008, saying essentially, "WTF?"
Really? He's blocked it? Surely we should block it. Hang on a moment. Well, tell him to unblock it. It's our... song.
This has gone back and forth for years, but in October it was posted on YouTube again, and today Prince was like, "eh, wtf?" and tweeted it out to the masses (since deleted). Hey, he's a creep, he's a weirdo, and he does not own this intellectual property. So, enjoy!
