Your Favorite "depressing"PV

[criminal]

aiko - Hoshi no Nai Sekai [definitely the best song + PV combo ever - has a relatively happy ending, though]
Ai Otsuka - Kumuriuta [it's not that happy.. D: kinda sad the way she's suffering..]
Ayumi Hamasaki - momentum
Ayumi Hamasaki - part of Me [coupled with the lyrics, it makes it even more depressing]
BONNIE PINK - Water Me [same thing, the ending is quite hopeful, but it can get a little sad in the middle]
Koda Kumi - Moon Crying [this one isn't that great.. but the idea behind the PV definitely is with how the moon can create illusions in Kumi's mind and stuff @_@]
Utada Hikaru - Passion [again, a great song.. the PV isn't that clearly depressive, but you kinda get that feel..]
