What were you listening to in the ‘90s?

As the Grammys draw near, we’re taking a look back at the most popular music of the last quarter-century. So here’s a little quiz: Of the 25 bestselling albums of the last 25 years (or technically the 24 bestselling albums, as Adele’s 21 enjoyed two years at the top of the charts), how many are in your iTunes library or CD collection or even, dare we say it, cassette tape archive?

Take stock of your tunes and take our quiz! And to those of you who have all of these, whose musical tastes span from Billy Ray Cyrus to Alanis Morissette to Lil Wayne to the cast of High School Musical: We salute you.
