All-4-One's self-titled debut proved that the quartet were exceptional vocalists, but the songs they sing often don't do them justice. Dividing their time between ballads and smooth dance-pop numbers, the group always sounds good, but they aren't charismatic enough to make weak material compelling. Nevertheless, when the group does have a good song -- like the massive hit "I Swear" -- the results are first-rate. ~ Stephen Thomas Erlewine
