Just listened to it (that's one heck of a music video) and I do like it, I prefer it to All the things she said too. I could see them doing it, it's a bit lighter too for Brittany's voice than some of the songs I've thought of for them.
I forgot to say welcome to the thread too. You appear to have the right level of excitement and exclaimation marks to join in
Haha, your last comment made me laugh a lot! Thanks for the warm welcome
