Big fan of Skateboard P. Pharrell has always been more than hip hop, he's a musician and an extremely talented producer and songwriter first regardless of genre. Even where he was doing bangers for Fabolous and Jada, he was doing NERD; when he was doing grinding he was doing Britney songs and then Justin, but can come back with Hell Hath No Fury. He also always comes across as a humble and knowledgable guy who just enjoys good music. I think he has had periods of weakness, but I think all genre defining producers have this - similar to Timbaland, they re-invent or re-focus and re-emerge. As he enjoys music so sincerely and is genuinely talented at crafting music, while he may have a few blips, hes probably always likely to bounce back. Never a sellout.
