Some discographies number mini-albums differently than albums. Some don't. Ayu counts mini-albums separately from regular albums (remember how she was saying that Secret was gonna be mini-album number 2, but now it's Full album number 8). It depends on how you wanna do stuff.

I don't number the releases at all (and didn't on my site, and still won't when it returns). It's just too confusing, and starts all these arguments on what counts & what doesn't count as a certain type of release. Just annoying really.

But anyway, last I checked, Oricon counts mini-albums on its album sale chart, since there really aren't enough mini-albums for them to have their own chart.
