I agree with what the last poster said. Eminem has a formula and he never switches it up. His first single is always an upbeat, poppy song that will appeal to suburban white kids (My Name Is, Real Slim Shady, Without Me, Just Lose It). Then the rest of the album turns out to be fairly dark and violent, and more of a ghetto "thug" album. That's where the good stuff is -- these first singles he releases are getting really old and are starting to sound the same (when I first Just Lose It, I actually thought it was Without Me).
Even though Just Lose It is hardly Eminem's best single, Eminem's work is at such a high level that this song is still superior to most stuff on the radio right now.
