Oricon recently asked a thousand men and women which artist of the opposite sex they would sing karaoke to.

The top choice by men was Ai Otsuka, known for many lively hits such as "Sakuranbo." YUI ranked second, followed by a tie for third between Miyuki Nakajima and Ayaka, while aiko ranked fifth.

Women, on the other hand, favored KinKi Kids. The next most popular choices were L'Arc~en~Ciel, Porno Graffitti, Mr.Children, and Kobukuro.
