Even if you have been living under a rock for the past three months, you (and everyone else in the world—from your loving grandma to the local postman) couldn’t escape the musical domination that was Adele’s 25 album. Released on Nov. 20, 2015 after a four-year hiatus, the project found the British singer taking hold of her pop reins once again. But before we get ahead of ourselves, we must not forget Adele’s previous (and also incredibly major) album—21.

Her sophomore effort celebrates its fifth anniversary today (Feb. 22), and in honor of the LP we at Fuse decided to break down its chart success while comparing the record to its older sister. Because what’s more fun than a healthy sibling rivalry? Dig into our roundup of 21 vs. 25 stats below.
