We've all been there. A friend wants to play you their new post-post-dubstep track. You have no choice, it's on. "It's good" you say, meekly. "Great snare sound". It turns out that it isn't just aspiring producers with a cracked copy of Ableton that want approval from anybody who'll listen – superstars are just as thirsty for feedback.

In a Rolling Stone interview, Seth Rogen reveals that Kanye West rapped the entirety of Yeezus, at that point unfinished, to an intrigued Rogen. He ran into Rogen in a hotel lobby in New York and dragged him to his limo to gain his insight on the Yeezus prototype. Rogen let slip how Kanye's openness inspired him and even changed his practices.

"Me and my wife had gotten some dessert and were in the lobby getting plates to bring back to our room," said Rogen. "And Kanye was like, ‘What are you guys doing? Want to hear my new album?’ So he takes us to this limo van and starts playing his album – except theres no lyrics only beats. So he raps the whole album and after each song, he stops it, like ‘So what do you think?’ We were in the van for 2 hours!

Now I realize the next person he sees that he knows is getting pulled into that van,” Rogen says, laughing, “But I learned a lesson from it – which is that Kanye is seeking input at all times. Processwise, it showed an openness and a fearlessness. We started screening our movies more and in rougher versions for our friends because of that.”

Rogen and Kanye have history – the comedian and best bud James Franco made their own version of Yeezy's "Bound 2" video. Watch it below, it's like Yeezy's, but hairier.
