Her cello skills are so good....I remember when I first heard of her....my sister was like "OMG my friend just showed me a creepy cello girl who looks like Ayumi Hamasak" and I'm like HUH? And then I fell in love with Still Doll....If she releases in the U.S I'll definitely go out to get it.
According to:

her album ranked in at the #47th spot on the weekly charts. Dont really know about daily though
