This beat is dope and 9th didn't even produce it, he's on the hook though as his alias 9thMatic.
The spitters on this track are all part of his latest venture "It's a Wonderful World Music Group." His label that he has put together to forward his love of the hip hop that isn't largely subscribed to and played on the radio.
I'm feeling the female spitter Rhapsody (not like that guys) she's got bars she doesn't go as hard as I've heard her on a few other 9thWonder productions. You should check out her group Kooley High if your into that Little Brother and Pac Div kind of rap.
