If there is anyone you're going to sample without permission, don't let it be Mariah Carey. Aside from being a diva, you already know she will come for you. A rapper/singer who goes by YTK did his version to Mariah's "Shake it Off," but he called his song "Let it Off." Yeah, he's talking about shooting. Well, an A&R guy was trying to get Mariah's attention with the little catchy song by tweeting that Mariah had 24 hours to respond, according to TMZ. You didn't think she wouldn't respond? Mariah responded to the guy saying they had 24 hours to respond to her lawyers with a GIF of her saying "GTFO."But was she joking or dead ass serious? Clearly, she didn't give permission to use her music. Apparently, the guy said Mariah was kidding, but was she really, though? And the guy also tweeted that Questlove is trying to help get the song cleared. Well, we will see. Do you think Mariah was kidding?
