Beyonce's "Single Ladies (Put A Ring On It)" tops the 5 million mark in digital sales this week. This is Beyoncé's best-seller. Beyonce's second best-seller is "Irreplaceable" (3,139,000). "Single Ladies" logged four weeks at #1 and went on to win a Grammy as Song of the Year.
Iconic and memorable. Beyoncé is the first solo black female to take a single over 5 million digital copies! (Rihanna, Alicia Keys and Janelle Monáe hit the mark first but as features)
