Why is Def Leppard's original "Animal" missing?

[Animotion]

...from the album Hysteria? I can only find de live version. But I want the original one. I have the LP, but I want it in a playlist.

Hey @Animotion and welcome to the community!

Unfortunately, Spotify is not responsible for missing music and removals of music that used to be available. If there's an artist/album/song missing, it's because the label/legal owner doesn't want it to be on Spotify or it is not available in your country (anymore). I suggest reaching out to the label and ask why this song is not on the service.

It's common that music is added and removed from time to time, even if it's older musIc.
