I forgot about her last single but I finally listened to it and it's so beautiful! I love her voice.
Not sure what she's been up to...would love to get those best albums! Seems like a nice mix.
She is in a musical called "Rock of Ages" you can check out the website here:

She also did an ending song for a show Hanakappa (hitomi did one as well I believe) called "うれしいこと" (Ureshii koto, or a happy thing) but I can't find the song anywhere.
Other than that...not sure what else she's been busy with. I was hoping for another studio album sometime soon
I love her covers but enjoy her original works too.
