"See You Again" from Wiz Khalifa and Charlie Puth just became the most-watched video ever on YouTube, but Charlie almost didn't get featured on it.
He actually co-wrote and co-produced the song, but the movie producer initially wanted a "name" to sing on it. A week before the movie came out, they told Charlie they were replacing his vocals...but he wasn't having it.
I said, 'That's great, your movie comes out in a week, and I'm NOT gonna give you the song.' I hung up the phone.
After that, he says they backed down. So his vocals stayed in there, and he also ended up heavily featured in the video. He didn't say who the producers wanted, but in an earlier interview he did mention that he recorded the vocals as reference...possibly for Sam Smith.
