Hikari?
Sakura?
Scramble?
Mainichi ga Otenki?
Or maybe an Aice5 one?
Believe my Love?
Or something totally different?
Like one of the 9423 insert songs in an anime?
I gotta say, my all time favourite Horie Yui song is "All my Love", which is also used as OP in Ground Defense Forces Mao-chan. Love the music, the lyrics and the music video!
#5. Sakura. Very nice for the first song on the first album, many of my favorite musicians had a much weaker start.
#4. Promised Love ~Daisuki x100~ - the 2nd inserted song from Dog Days. The reason why i at all wanted to come down from anime and started to look for her regular songs.
#3. All My Love from Sky. Amazing atmospheres, amazing story-telling-like tone, very inspiring theme (btw, i never bothered reading lyrics yet, that's not something i like in music).
#2. Pure from Kuroneko. I'm surprised to see this song so much underrated. A sort of melody that doesn't show up for the second time in your life.
#1. Nano Desu. Yay, if you ever become cold-harted enough to look for a reason to love Hocchan, remember this one! :3
