Where is "breathing underwater"?

i wanted to change my player anthem song in game today and i wanted it to be the song "breathing underwater" that has been in the game for a long time, yet when i go to add it, its not in my profile account anymore. and I'm worried they removed it for some reason. Anyone know what happened to it? i swear it used to be there because i used to have it set as my anthem for ages in the past
