Of course it will go down in history. It's broken records and made it's own. history.
As far as a classic though, idk.
Classics are determined not only by sales, but by the following, and how it stands over time.
For example, in the pop community "The Fame Monster" is a classic by some, but things like "Thriller" and "Ray Of Light" are not only classics by some, but almost universally inside and outside of the Pop Music community.
