Upgrade U Lyrics

Lyric discussion by BeBrave 

Cover art for Upgrade U lyrics by Beyoncé

I'd like to know what "you know I used to beat that block: Now I be's the block" means... does anyone wanna interpret it for me?

Because then Beyonce goes on in [verse 1:] "I hear you be the block But I'm the lights that keep the streets on"...

So I understand what Beyonce is saying, I don't get what Jay-Z's lyrics mean??? Because it sounds so badass when he says it... Sounds really creative, just wish i knew what it meant.

peace...

My Interpretation

i think he means that he's more important now, he doesn't beat the block anymore, he IS the block now
