Query: People, this a great album

I can't believe why this thing didn't sell more than it did.(10 million copies) It has at least five potential singles that could've made great videos. The best tracks are the first four, Butterflies, 2000 Watts, Whatever Happens, and Don't Walk Away. The worst song is Cry, which goes a little slow for me. Please buy this!!!! You won't regret it!!!!
