It was reported last month that Madonna’s upcoming 4th greatest hits album would be called Iconography. However, it has been officially annouced (I think last month) that it will actually be called Celebration, which I like much better.
Here is the Warhol-inspired cover art for her album, which I love. I like that she went with an old school Madonna shot rather than something new.
Additionally, here are some short (5 seconds) promos for her upcoming release in September. Kind of neat!
