Straight to the point. Just list five J-Pop artists/bands and the first song of theirs that you listened to. It doesn't have to be the song that got you to like them, just the first song, full-stop. Oh, and I mean five artists that aren't Ayu.

You can describe how or when you listened to the song, too. I'll start off.
[P.S.] If a moderator feels that this should be moved into the Posting Games forum, then by all means, do so. I just wasn't sure which forum this should be in.
01. Kumiko Koda — real Emotion.
[ I was really into FFX-2 at the time. It was a couple of years ago. I was looking for JADE of SWEETBOX's version (the English one featured on FFX-2) and I stumbled across Koda's and gave it a download. ]
02. Do As Infinity — Fukai mori.
[ Inuyasha's second ending. Duh! XP ]
03. Hitomi Shimatani — Garnet Moon, technically.
[ I was browsing random avex pages, and I stumbled upon Shimatani's. It wasn't long ago, 'cause the CM for Heart & Symphony was up there. Garnet Moon was the first segment, so I watched that. So technically, Garnet Moon is my first. But right after that on the H&S CM, Falco and Sky High play, so they're firsts too. ]
04. hitomi — I Am.
[ Inuyasha second opening. ;D ]
05. AAA — BLOOD on FIRE
[ I was curious and wondered who they were, so I gave them a listen. Yay. :3 ]
