iTunes ratings?

[Melrose]

So iTunes is pretty big right?

Well, I just downloaded it and went to look at the ratings of Ayu stuff. But A COMPLETE only has 3 stars! Compared to 4 for even GUILTY and Secret. This is so strange? The album sold a lot too.

But my question is, Secret has 4 stars and "v a" instead of 5th star. Does this mean it has 5 stars or what? Actually I just realized Startin' has 3 stars and v a too. :/ Whats it mean?

OK, second question, when I got to "All ayu songs" the popularity order is BLUE BIRD > Mirrorcle World > STEP you > No way to say. But when I search for Ayumi Hamasaki, I get a list at the bottom of songs with popularity order BLUE BIRD > HEAVEN > JEWEL > Together When > etc. Wtf? This second list is really weird. Bold & Delicious and talkin' 2 myself are near the top of the list, above much more famous songs like Moments, etc.? *confused* ALSO pretty much ALL songs except the first 30 have a popularity of 0-3 stripes. o_O

Thx in advance.
