has Jimmy and Terry been producing some Usher tracks?, Jimmy was up for some Grammy

They were nominated for Producer of the Year (for the 10th time!). This is what it says on the Grammy.com site:

Jimmy Jam and Terry Lewis are nominated once again as a team on a slew of great recordings, including Janet Jackson's Damita Jo; India Arie's "Eyes Of The Heart"; and Usher's "Simple Things," "Truth Hurts" and "That's What It's Made For."

So yeah, they did produce a few Usher songs. And they didn't win the Grammy -- John Shanks did.
