I was browsing the Neptunes discography last night and your point re Premier returned to me because at a certain point they started working with people like Katy Perry and I wondered if they also priced themselves out of working with anyone but the richest artists.
Obviously they were working with big artists for a lot of money from early on but I thought that was interesting.
Well back to what I was talking about in regards to Premier, their market value is dependent on their continuous success. Look at Philly's Most Wanted, that album is wall to wall Neptunes production and its a rap fan classic but it sold fuck all right? When a label sees you do that, they get apprehensive, like "Think of all these records you could have given JANET or BRITNEY or JUSTIN".
Actually its been discussed but a lot of The Neptunes work for Timberlake were rejected submissions for Michael Jackson. I have always humored the notion that Pharrell was probably incensed and was like "OH WORD!?!?! WORD!?!?!? WE NOT GOOD ENOUGH FOR YOU!?!?!?..... YO CHAD, CALL UP THE WHITE BOY. WE GON SHOW THIS MOTHERFUCKER."
So now at their point in their career, it doesn't suit them to work with just anyone because then why would they be allowed to do what they do? Pharrell's last album is a clear extension of the accidental hit in "Happy", "Happy" was just meant to be a closing theme for a movie franchise, and instead it revitalized the perception of him as a solo artist. Remember how long the industry balked on "In My Mind" because the singles he sent out for that wouldn't blow? And honestly I do believe "In My Mind" would've been a great album to hear; but the industry wanted to ensure those songs could either be hits or nothing. This was a decade ago when the industry seemed like it would die any minute, and everyone was in a panic, trying to give away free albums and all kinds of wild maneuvers. Now everything's codified and stable-ish again, because they starved out a lot of the various music piracy breakdowns and adapted.
And of course, that's where Pharrell is right now. He is at the victim of an ailing industry... Not dying, but rather like an addict that can no longer support its former lifestyle and has to beg and scrap for every detail. The streaming wars going on right now between Apple, Tidal & Spotify are perfect examples, especially when musicians are transitioning into content providers to achieve celebrity. So Pharrell can't make decisions of artistic liberty because his main source of income is to serve others and try to support artists, its what he's used to as being a rap producer who now has transitioned into being a general producer for pop. His lifestyle is built on working with and improving others, he can't just make a break from the industry and go rogue a la Prince, he was never that guy. But even someone like Prince always comes slowly back to the business that got them where they are, because they can't sustain the position in the world without it. Even outside of pop/rap/R&B, look at Radiohead. They came back to the majors.
