lol at comment below. look like it's u know nothing about music. it was just a sample. the reason why they called it "feat." cuz boys wanna feel cool that such a legendary musician featured with them. If Otis was alive, not sure that he wanted anything in common with hip-hop.
All the music elitists dissing this because it samples Otis Redding should fuck off. It's not fair to hate a song JUST because it uses an artist you thought was "sacred". Honestly, if they didn't sample Otis, would you hate it so much?!
