Ava Max - Diamonds & Dancefloors

If its just Not Your Barbie Girl instead of a new track…

It's a new song called Choose Your Fighter!

I do wonder if her being involved in this soundtrack is why she's been doing Not Your Barbie Girl on tour though. Seemed like a very random choice, but now it makes a bit more sense.
Saw her last night and the show was a disaster / comically short but I had fun! She did like one massive medley of all her songs (horrid setlist) and kept pretending she was British.

Was this part of a festival or something? Sounds pretty different from her regular tour dates.
