She might have naturally picked up her "new accent", or she might just be trying to fit in haha. If there's that slight chance in a blue moon that an American media wants to interact with her, her accent won't be too strong or something.
Thank you for sharing the song!
I'm quite impressed with the song. It's not what I normally voluntarily listen to but it sounds nice and radio friendly.
I'm a little worried her voice doesn't really match the songs style, but I dunno. There's a couple of nice higher notes she hits. I generally feel positive about it.
I really like her little background voice. The one that goes "never forget never forget" and her little voice before the chorus. It's a cool little melody.
