4. Lady Gaga
With 124 album sales under her belt, Gaga’s best-selling album is still her first work, The fame. This album was triple platinum certified. While she is famous for her sky-high platform shoes and get-ups made of raw meat, Gaga has given up plenty of gems in her own work. She’s one of the best paid musicians in the world and besides an impressive bank account, she won 12 Grammys and even some Guinness World Records.
