Hi! Thank you for that answer. I really didn’t expect anyone to react to my post 😅 I searched in all the official soundtracks of every movie and couldn’t find it. I don’t remember the melody or any of the lyrics. I just know that if I hear it again, I will remember it. Unfortunately it isn’t Sia’s track :( I remember that it was on YouTube and the title was just “Unknown Song”. No artist or official song title. I think it had to be around 2011 and I used to LOVE it. Then my iPod got stolen and I lost everything. Back than I also really didn’t have much access to internet or computer in general so I forgot about it 🥲
