Almost nothing, musically. But the divergent artists have attained multiplatinum album sales in the Recording Industry Assn. of America’s October sales certifications, reflecting the increasing fragmentation of consumer taste during the last three years.

Vandross has hit 2 million in sales for his “The Best of Luther Vandross–The Best of Love,” released on Epic; Guns N’ Roses is now at 4 million for “Use Your Illusion II” on Geffen; Wynonna Judd’s “Wynonna,” her first solo album after splitting with mother Naomi, has moved 2 million Curb/MCA units; Extreme’s breakthrough album “Pornograffitti” has sold 2 million units for A&M; and Adams’ “Waking Up the Neighbors” on A&M has now sold 3 million units.
