WHAT: It has been six years since pop star Jesse McCartney released a studio album, plenty of time for the singer to develop a theme for the material on his new "Technicolor" album. "I had a theory, and I still have this theory that we're all on planet Earth for a very short amount of time, as everyone knows, and basically we're here and we're searching for that one person that validates you or see you for what you're worth," McCartney told MTV.com.
