Let me correct what I said. Longevity > Massive peaks. Sales can't be consistent due to change in music consumption. Bey will be one of the best seller in the future. I'm not sure exactly her current stats, BB didn't update her single sales, which probably around 60 M. She has around 18 M albums ( soon it'll be 20, YAYYY!!), 15 mil Ringtones, DVDs, Soundtracks, EPs are unknown. Wow. She has at least sold 90 M+ records in US alone. Now, imagine streaming is included, WW is included. If DC is included, her stats are crazy. Thanks to her longevity tho as her catalogue sales is very impressive. Rih will be the best seller probably. Her singles are just too much. However ,it didn't match her album sales, tours, earnings. And she don't really have impact as most of her videos and outfits are not memorable.
