Anna Tsuchiya Blue Moon & Hannah Montana One In A Million???

[Celaphorce]

Okay I just downloaded the ENTIRE Anna discog thanks to Karen, anywhoozer, I was listening to her songs randomly and Blue Moon came up and don't make fun of me but I love some of the HM music cause it's kinda catcy, so I eventually listened to One In A Million, and I'm wondering if they sampled Anna's song because I started humming and singing along to Anna's song even though the words are completely different.
