Every Friday Billboard is asked a "burning music question."

Today's is: Who has totaled more record sales, GUNS N' ROSES or METALLICA?

Billboard's Gary Trust answers:

"Utilizing Nielsen SoundScan data, which dates to 1991, Guns N' Roses have totaled 24,914,000 albums sold in the U.S. 1991's Use Your Illusion 2 leads with 5,587,000 units, followed closely by Use Your Illusion 1, at 5,502,000.

In that span, Metallica has sold 52,271,000 albums in the U.S., led by 1991's Metallica with sales to date of 15,525,000.

According to the Recording Industry of America (RIAA), whose data encompasses the bands' entire careers, Metallica leads Guns N' Roses, 59 to 43.5 million. Among all artists, Metallica ranks 18th, Guns N' Roses 30th.

It does help Metallica that the band has released more albums. The band has placed 14 titles on the Billboard 200, compared to G N' R's eight."
