I absolutely love The Black Parade. It differs so much from My Chemical Romance's past albums, which was their intention. All of the songs on it differ greatly, too. This album has everything from fast, almost crazy songs like "House of Wolves" to slow, sad songs like "Cancer." There are even a few songs that are a mixture, like "Disenchanted."
There isn't a single track I don't like. All of them contribute in their own unique and creative way to the story of this concept album; the story of "The Patient," a dying man. The songs tell the story of his life and his reflections on it. The concept in itself is creative.
Overall, I really enjoyed listening to The Black Parade over and over. It's the best money I've spent in a long time, tied only with the other 2 MCR albums, which I own.
