The No. 1 position on the pop album chart has been nicknamed the Dogg House--in honor of Snoop Doggy Dogg's frequent residence. He's back "home" again, with his "Doggystyle" reclaiming the top spot. Many Jodeci fans are now finding out that the vocal group has a new album. Some didn't notice when "Diary of a Mad Band" came out the week before Christmas. But the album is now picking up steam, zooming from No. 27 to No. 8 in its second week on the chart. Two Top 10 albums, Tom Petty's "Greatest Hits" (No. 9) and Aerosmith's "Get a Grip" (No. 10), probably will drop out of the elite circle next week. Both climbed in recent weeks because they were popular Christmas gift items. Mariah Carey's "Hero" is still the top pop single.
