Talkin' 2 myself - I loved the concept of this PV and I loved that she attempted to do a little dancing for us! It was very dark, dirty and gritty just like the song.
decision - To me it's like an upgrade version of evolution. It was filmed with a very J-rock vibe and the lights and camera angles make it very visually appealing in my opinion. Sure not a lot goes on but Ayu looks liked great, the song is great and the video looks great. What more could you ask for?
glitter/fated - They're not exactly my favorite but I really appreciate the effort. (Technically it doesn't really belong in this list lol!!!!)
Together When... - Definitely one of my most favorite songs and PV. Both are extremely personal and it was very simple, clear-cut, not a lot of theatrics. I think if Who.../Ever Free/or Mem. Add were made into PVs, they would be a lot like this.
Marionette - Come on... You can't tell me you think Marionette is bad! It's MARIONETTE! xD; Sure you may not like it, but you can't think it's crap! You'd be crazy LOL.
Mirrorcle World - MW took a long time to grow on me to be honest. But it is very visually appealing. Ayu looks great, she's in a foreign location and she has GREAT costumes. Seriously the best clothes in a PV I've ever seen her in. I also love the head shot with the eye-lashes. <3
Days - Very typical story, very nice scenery, very nice hair and outfit. People may have their nit-picky issues with Days but it's far from a
bad PV and Japan would definitely agree.
GREEN - A foreign location again. The only downside about this PV is the directing/editing. Ayu is flawless. Scenery is flawless. Nuff said xD;
Sparkle - Sparkle PV isn't really what I had in mind when I was imagining it but love it or hate it, you can NOT say it's boring, not innovative or unoriginal.
Curtain Call - I may be in the minority of CC lovers, but I LOVE this PV. I love its simplicity, I love how dressed down she is, I even love its flaws. I think the dislike for this PV stems from nit-pickiness again. "She's walking to fast" "It's all one scene" "Boring, unoriginal" blah blah blah.
Sunrise/Sunset - May not be the best PV to
watch, but it was definitely the best PV to BE in. It's nice that she has PVs every now and then that fans get to join. As a fan myself I greatly appreciate that.
You were... - I adore this PV. I'm not ashamed to admit I cried when I first saw it lol. I think I have a thing for simplicity because this is one of my top favorite Ayu PVs. Again, not too much going on, not much of a story. But it's visually stunning and it's open to great amounts of interpretation. I find that (some) Ayu fans like to be told a story, beginning to end, don't leave out any detail because if I don't get it I'll call it "boring, dull, crap." Open your minds people.
BALLAD - EXTREMELY beautiful PV, great contrast, love the animated cats. Even though the story is well told, it is still open to interpretation, just like You were...
Microphone - I know some fans feel this PV is dumb because she wasn't in it enough, but even Ayu is big enough to share the spotlight even if some of you aren't (same goes for blossom). I love this PV, extremely great use of transitions. Nice to see some British talent.
Don't look back - Ourselves part II. Very simplistic yet super powerful statement. It's awe-inducing, draw-dropping and creepy as hell. Haters to the left.
Lady Dynamite - This PV gets a lot of hate but I think it's just from nit-pickers who have spikes up their butts and are
NO fun.

Just kiddinggggggggexceptnot...
Sexy little things - This PV gets a lot of love. Personally, I'm only a big fan of her costumes. I'll let the lovers tell you why it's so great LOL.
