Well, I hate to break it to you but they've already announced Tiana's Bayou Adventure will have all new music because it's a sequel. So, it doesn't really matter—music wise. They're going to do what they want anyway.
It really wasn't. It's been compared to being on par to The Great Mouse Detective in terms of box office performance. Not a flop, but not a resounding success either. It ranks last in the princess movies in terms of box office performance.
