If anyone else is questioning Adele's place as one of the greatest artists of all time, this latest information should be enough to silence as all. Not since 18 years ago has any artist's single sold 400k in each of its first three weeks - but Adele's powerful ballad has now achieved what Elton John’s “Candle in the Wind 1997” did. Note that only 12 songs have topped 400k (digital or physical) in its weekly sales.
