Madonna's new ABBA song

The Motorola clips of Madonna's new single, Hung Up show off a very ABBA sample which initially irritating, has grown on me the more I listen to it. It's commercial when I hoped for avante-garde. But, how can I really have expected different? She needs something top 40 this time around to sell well. Honestly, I couldn't care less about sales, but I'm sure in high quality and packed with other album tracks, it'll be a gem in my usually rose-coloured eyes.

*EDITED - See above post for why.
