How good is Taylor Swift’s 1989 album?

How long has Taylor Swift been on top of the music world? You could say She was not on top at some point in Her career but if someone was above Her She was still relative and still at top 5, what other artist can say that? That is a 10 year span that She has been at top or near the top and one thing for sure She is definitely at the top today, October 30, 2014.
