Hiro Nakamura is a character in the TV show Heroes who’s superpower is time travel. This refers us back to the previous line:

I go back to when it was cool to be you

When you stare in the rear you end up committing suicide like Stewart Shakir. Stewart Shakir was the executive that replaced Jay-Z at Island Def Jam after Jay left at the end of 2007. He was found dead in his house from a self inflicted gun shot wound in November 2008.

I’m pretty sure this is about Def Jam and his departure in ‘07 after being there in limbo for over 2 years. Budden doesn’t call out Def Jam by name in this verse, but I believe it’s just because he doesn’t want to give them any more attention.

On “Never Again”, he says:

I swore I’d never say another word about a Def Jam

This continues the theme of both the preceding breath of fresh air and traffic jam lines.

Common is here to help with the resurgence of hip-hop and to ensure it moves along in the way that’s best for its future.

Several ways to see this:

• Common makes both conscious (pro-black) and hardcore (semi-automatic) music, neither of which gets played on the radio for people to jam to while being stuck in traffic.

• For Common, making music is akin to doing black magic. Thanks to this, he and his people won’t get stuck in the traffic jam that is the congested music industry.

Common’s rhymes don’t usually target the people at the top of the pyramid, i.e., those who are well-off in life; they target everyday people – the commoners.

Common is giving a name for his fans: Commoners. This is done by some other artists as well; Tech N9ne, for example, calls his followers “Technicians”.
