From "No Church in the Wild":
We formed a new religion
No sins as long as there’s permission
And deception is the only felony
So never fuck nobody without telling me
I hadn't really listened to much Kanye West until My Beautiful Dark Twisted Fantasy which pleasantly surprised me.
The crudeness makes me think he may be talking more about swinging than about poly, but his openness seems to be broader which makes me think maybe he is talking poly.
I just saw the lyrics on another site and have started downloading the album now, so I haven't heard the whole thing yet, but I thought I'd share.
Even those who don't really like much rap/hip-hop might want to give it a chance. I certainly did like his last album.
