That song was written by Chris Cornell. DC wrote other songs with Chris and others for the CD, but this is the song that they felt was a good transition song from his "coronation single" to his "harder rock". You know - ease those AI watchers and listeners who love "Time of my Life" into the rockier songs. It is a good blend of pop and rock.
I think you are right and DC can be successful like KC. I recently got her last CD and listened to it once

Looking forward to her new CD that is coming out early 2009. I am hearing great things about it.
As far as I know he is still with Kimberme!
