I love the Neptunes and N.E.R.D., and they do have a very hot sound, but the over-Pharell-ization of music today makes things a bit...boring? The Neptunes are the hottest producers these days, but case in point: Beautiful, Snoop Dogg's new song with Pharell Williams (the most visible member of The Neptunes/N.E.R.D.). It's tight and sexy but it gets predictable. This quote by Sasha Frere-Jones in the Village Voice's Pazz and Jop ('Tune versus Tim, as in Timberland) issue says it all:

Chad Hugo and Pharell Williams of The NeptunesThe Neptunes are the first important producers of the 21st century, happy children of the loud, brassy world of digital audio. It's not just how their beats return again and again, deathlessly big like a can-crushing machine. Their ideology is digital. The sounds they pick are clean and the pop thrills they seek are rarely idiosyncratic.

Neptunes produced songs you've heard, and if you haven't, then Gothamist is watches too much MTV:
Boys, I'm a Slave 4 U - Britney Spears
Like I Love You, Rock Your Body - Justin Timberlake
Hella Good - No Doubt
Work It Out - Beyonce Knowles
Girlfriend - *NSync
Hot in Herre - Nelly
Honey (Remix) - Moby

And their upcoming projects look as widereaching: Foxy Brown, Beyonce, TLC, Loon, Korn, Blur, Rosco P. Coldchain, FAMLAY, Kelis, DREAM, Limp Bizkit, Blink 182, Marylin Manson, Popa Roach, Sugar Ray, Kardinal Offishall, Sean Paul, Ja Rule, Taxi 3 Soundtrack, Britney Spears, Mystikal, Super Cat, Vanessa Marquez, Kelly Levesque, Clipse, NERD. The Neptunes on their label, Star Trak Music.
