UB40 is a "reggae-ish" type of band, more on the poppy side. They've had some minor hits in the U.S. - including "Red-Red-Wine" (twice), and a remake of "I Can't Help Falling In Love With You." And sure, they don't really fit the reggae profile, and aren't really taken seriously in the reggae community, but truthfully, their music isn't that bad.
Their song "Cherry, Oh Baby," is a classic reggae cover (this song was even covered by the Stones), and has a really slow reggae groove to it. The song is about a man who lusts after a woman, who apparently hasn't shown much interest in him.
The chorus is addicting, and the bass-line overpowers the song. Not a bad effort by UB40.
