LL Cool J closed the 2013 Grammy Awards with Chuck D, Tom Morello, Travis Barker and Z-Trip. Now he's releasing the song he performed.

"Whaddup" features all the aforementioned and is from Uncle L's new album, Authentic, due in stores May 7.

Because CBS cut the performance off during the Grammys, it was hard to tell whether or not the song was any good. Younger fans were probably scratching their heads -- why is the guy from NCIS rapping? -- while old folks were likely glad to see hip-hop finally get some shine.

But sometimes it's best to hear a new song removed from the celebratory manner in which it's revealed. That said, "Whaddup" is actually pretty good. But don't let us sway you. Take a listen and let us know what you think.

Should these guys hang it up or keep rocking?
