I'm talking about groups that release albums. The thread creator just wasn't very forward-thinking, that's all.

What theme? This is an expansion, not a theme. If it were a theme, I would add movies or something else to the albums.

There isn't one for groups. And I'm not going to create a separate thread for each one, because it would be too prone to spam.
