Nas - "Hero" (Feat. Keri Hilson) (The Jones Experience/Def Jam)
By all musical standards, the hard-brawling, hard-hitting MC we've come to know as Nas should've expired years ago. Nonetheless, he's still churning records at a decent rate, causing purists to cheer and critics to take a second look. No matter what side of the fence you fall on, "Hero" gives us all a reason to care again.
Pros

* Nas is still in top form after 16 years
Cons
* Nas sounds muted while tackling a bold topic
Description
* "Hero" is the lead cut from Nas' untitled album
* The song was produced by Polow Da Don
* It touches on the controversy surrounding his previous album title
Guide Review - Nas - "Hero" (Feat. Keri Hilson) (The Jones Experience/Def Jam)
"Hero," which features Keri Hilson, is the lead single from Nas' untitled 9th album, and it pretty much sums up not just the story behind the album's title controversy, but Nas' current status in hip-hop. It's the perfect soundtrack to the movie SuperNas, in which lead character Nasir Jones takes extreme measures in a bid to reinject some bite into hip-hop.
For all his brave posturing, though, Nas sounds rather muted on "Hero." His explanation borders on apologetic: "Still in musical prison, in jail for the flow," he rhymes, after insisting that the title change had nothing to do with pressure from his label bosses ("For the record, L.A. [Reid] and Doug Morris is riding with it"). Ironically, Doug Morris' name was actually censored on the album version of "Hero." Go figure.
"Hero" is not Nas' best single ever. Truthfully, he's capable of so much more. But, give Esco credit for rocking his Sunday best flow over Polow Da Don's catchy beat. How can you not cheer for hip-hop's favorite "Hero"?
