So many questions relating to Ayu!

[Warren]

Alright so i'm so new to J-Pop I just started listening this year. which has only been 29 days haha.

I have been into pop from different cultures for a long time but there is so many odd things in J-pop that I don't get, and some things Ayumi does specifically.

1. Why is all the comments/likes/dislikes disabled on her official YouTube channel? I noticed this with Utada as well?

2. Why does she not have a 'Vevo' I know quite a few artists don't have one that are well known. But it's still odd to me when someone as successful as Ayumi is. Is it to do with her label?

3. Why does she release a lot of her music videos on her official YouTube account shorted? Is this because she wants people to buy the the DVD/Blu-Ray releases that come with her albums? I first thought she was cutting Crossroad because of the burning LOL, but then notice a lot of her videos are shorted.

4. Why in the late 90's did J-Pop artists release portrait styled single covers?
for example https://en.wikipedia.org/wiki/Poker_..._Hamasaki_song)
I also noticed it with Olivia

So weird hahaha but interesting!

5. Why are none of her songs on Spotify! Is it to do with her label?


6. What's a good price to pay for "A Clip Box 1998–2011" and is it worth buying

Sorry for all my questions! Will love everyone who rids me of my confusion!
