She has a very unique voice, with just a tiny bit of rasp to add more depth and personality. This is like the ultimate cozy song to enjoy while wrapped up in a blanket with hot chocolate, watching the snow come down. She is so cute, especially with her smile.
I'm happy we've mostly avoided snow here so far, but it sure is nice to look at. That cabin in the snow looks so peaceful. I can see why she was/they were so popular.
Butterfly Effect and Workaholic are my favorites, with Butterfly Effect taking a slight edge. I do think Snowball is a super nice winter song.
