What song is this?

Hey! So I've been trying to find a song?? Or the group. I haven't seen it heard of them since 2014 back when I was a kid. But the group had a A in the name but I can't remember.. the song had the cover art of like faded people and sort of like a Jellyfish? something like with colors in the corner.. I need help finding it. please anything helps especially since this has been bugging me for years now. I know I didn’t give a lot but that’s all I can remember.. anything helps.. please and thank you
