Query: Don't waste your money

Unless you REALLY like the song and are an avid Madonna collector, pass on the single for Sorry. The original is great, but it's already on the album, so track 1 is almost worthless. Track 2 and 3 are good, but it goes downhill from there. Track 6 is horrible. I'm listening to it now, and its not a dance mix.If you want a good single, turn to Hung Up. And if you can find an inexpensive copy of Sorry, give it a try, but don't waste your money.
