Hearing the last will and testament of the Notorious B.I.G. is an offer no gangsta rap fan could refuse, so Life After Death‘s No. 1 showing, with more than 689,000 copies sold, seemed virtually preordained. (In a fitting twist, unauthorized advance sales of the album had already landed it on the lower rungs of last week’s Billboard 200.) At the other end of the musical spectrum, Canadian chanteuse Celine Dion’s Falling Into You ascended to No. 2 on the wings of her Oscar-telecast performances. And in the week’s most surprising development, U2’s Pop disco-danced its way straight out of the top 10, making room for the Selena soundtrack. !Ay, caramba!
