So, I was reading Britney's and Gaga's respective Last.fm info pages.
Lady Gaga:
Quote:
The following year, music producer Rob Fusari dubbed her Lady Gaga, inspired by the Queen song “Radio Gaga”. After this she recorded her first two songs as Lady Gaga (Fever and Wonderful) on Def Jam records, but was later let go.
Britney Spears:
Quote:
Having sold more than 100 million records worldwide, she is one of the most influential and popular post-2000 icons of music, with five #1 albums on the Billboard 200 and The United World Chart. Spears is by far the most successful musician of her generation and one of the few young musicians to appear on lists of best selling music acts of all-time. She also holds several world records.
