New Video--Love Lockdown

What is this Coming to America, Michael Jackson Do You Remember The Time non sense? Has Kanye gone off the deep end? lol Just playing. The song, given the elements in the video, actually makes a lot of sense.

A few questions--
I wonder why he decided to premiere the video on The Ellen Show?
Is this song a dedication to his recent break up with Alexis?
Where is Kanye's inspiration coming from for the new album?
