This is so sick. I've gone through quite a bit of their other material but haven't found any songs that sound much like this one. Similar recommendations, anyone?
The lost akiba tape (Fly away) sounds like this as well as 高橋玲子 (Takahashi Reiko) - ラブソングは唄えない (I can't sing Love Song/Love song I can't sing/Rabu Songu wa Utaenai)
