There's nothing too much different in this sophomore effort in comparison to Sean's debut. "Tomorrow" uses quite the same recipe than its predecessor: heavily synthesized beats with average singing and catchy, well-humored and lovesick (mostly on the second half of the album) lyrics, but with a little reggae-style ("Island Queen") in between for a change.
Sean and his producers played the safe card here, and this strategy might prove to be well chosen after all. Too much innovation on a second album release could ruin badly the expectations for those who have waited to come back for more - of the very same thing.
It's worth taking a shot, definitely.
