WHEN YOU CONSIDER THE SUCCESS
HES HAD AS A SOLO PRODUCER
IT LEADS ONE TO BELIEVE HE WAS
DOING ALL THE HEAVY LIFTING.


Then they are being misled, because you have to consider the following:
1) Neptunes were on fire 2000-2006 then suddenly they weren't anywhere as near dominant. The hits started to dwindle
2) Pharrell's
In My Mind was dope, but it wasn't successful
3)
Hell Hath No Fury vs.
Lord Willin. When "Grindin" dropped, it shook up the world. Nothing on HHNF had that kind of impact.
4) It wasn't until "Get Lucky" (a song that only features Pharrell, but people think he also produced, but didn't), "Blurred Lines", and "Happy" that Pharrell really blew and people started crediting him solely for EVERYTHING including the work he did with Chad as The Neptunes.
There was a point where people said Chad was the mastermind. Neither was the case as both were integral parts of the Neptunes sound and when comparing Chad and Pharrell together to the production they do solo, it is empty as something is missing.
