Think about it though, a real fan would be more than willing to be open about the direction that their favorite artists are taking.
Consider Tyler as a prime example. He has followed Pharrell's masterpieces for the longest time! P came such a long way from making Tape You, to putting out Frontin', In My Mind is a classic and inspirational album, being named the 2000s number one producers as The Neptunes, and as of recently been such a popular name with number one hits and winning Grammys, he's not rapping as much anymore but his instrumentation has progressed phenomenally.
Tyler lived through that as a fan and loves it as a fan; coming to grips with moving on from your favorite artist is a sad thing. Pharrell did say You Can Do It too, and I believe, firmly, that Tyler should go this route, it is his turn to explore. With his lifestyles, with his sounds, and overall with exploring the world with his new-found wings. Tyler wants to spread the positivity, and if you think that you can't then you probably won't, but that isn't the focus... it is about shifting the perspective of the listener if they so want. Pharrell is influencing the world. Now's the time to play Smile. (Fuck, I'm up real late, I don't know what the fuck I'm saying but it sounds right. Thanks.)
