I NEVER understood. I haven't seen, or heard for that matter, anyone compare these two artist. The only people who really compare them are the people here. There is no comparison, they are two COMPLETELY different artist. The don't even sing the same type of music for God sake. This whole battle between the two of them has been COMPLETELY fabricated by the people on these MBs. I could understand Mariah vs. Whitney. I could even understand Mariah vs. Xtina. But Mariah vs. Madonna... wtf. Some people need to seriously get a life because this is just a ridiculous case of uneducated dummies trying to make something out of absolutely nothing!
