Adele hasn't had a album out since 2011 & sure it sold a lot but times have changed now. Many artists have been affected by the albums sales declining but not Taylor.
We'll see what happens when Adele releases her new album, until then its all TAYLOR & her monstrous 1st week sales.
That's so amazing and expected at the same time. Just shows that consumers will buy music even if it's available illegally if they really like the artist. Taylor just can't lose.
