Very few of these are actually weird titles.

I think some people are misunderstanding the point. Post songs which have weird titles. Not the titles of weird songs.

Mine favorite titles are:

i ～crossin' the star～ (Kimura Yuki)
Reason Reproduction ～flash-forward mix～ (Tamaki Nami)
Violet Sauce (Spicy) (Amuro Namie)
Body Feels EXIT (Amuro Namie)
Shine We Are! (BoA)
