Guitar Chord: Listen! - HTT K-On
Title: Listen!
Artist: Hokago Tea Time (HTT)
Anime: K-On
Comment: Actually, HTT is a band name in the anime. I don't know if HTT really exist in this world. If you don't want it, I can say the artist is Hikasa Youko (isn't it?), she is the seiyu (voice artist, the one who doing dubbing) for Akiyama Mio in K-On.
