The only place to hear new N*E*R*D music these days is checking out the Spongebob Squarepants soundtrack. "Patrick Star", the trio's third release from the record, is a required listen for the Pharrell stan, but may lose anyone else's interest if you're over the age of ten.
With that being said, there's plenty of the instrumentation we've been hearing the Neptunes experiment with over the last 15-20 years, and just picking that out of the kid-friendly record may be enough. As far as some new material from the group that's aimed at adults, we'll just have to wait and see.
I too would have envy
If I lived above the water
I don't blame the sky for
Being so blue
