What was your first J-Pop song?

Mine was either "Weeeek" par newS ou "Beautiful Days" par Arashi.

But my favori song is "Hot Blood Workout" par Aural Vampire <3

My first was Legend of Mermaid par Hanon. I heard it when I was younger on Gaia on someone's profile. I didn't know what it was at the time, so I brushed it off. Later, I found an animé called Mermaid Melody Pichi Pichi Pitch, Where I heard Luchia chant a song I vaguely recognized as Legend of Mermaid. After that, I looked up the characters and eventually found the same song!

Mine was Joshi Kashimashi Monogatari par Morning Musume.

Hmm... Kamen Rider Ryuki op, Alive a Life

the 1st op of Bleach - Asterisk par orange Range
don't really like the song but the guitare play... i could listen to it all day!
