In Finnish drama called "Salatut Elämät" [Secret Lifes] There was once this character called Oona, who was a fan of Japan, and in one episode, ayu was mentioned : D

They don't say anything important really, Oona sees the CDs and comments:
"What are those? Oh, that is good one. Ayumi Hamasaki". [They also mention SMAP, btw, Oona says "Ayami" though XD]
I think there was some other ayu mention in some program or something too, but I can't remember it :/
