Bey was 22 when she released the set in 2003, and the hype around it was huge. 'B'Day' will always be my favourite Beyoncé album, although 'Dangerously In Love' was fairly solid for a debut. 'Naughty Girl' and the Sean Paul assisted 'Baby Boy' were real bops, and 'Crazy In Love' remains a classic! Check out the stats for all of her solo projects below.
Dangerously In Love - 5m
B’Day - 3.4m
