Mariah v Eminem - I personally am not fond of either of them. Sure I listen to a couple of their tracks but their personalities? No way. They're both a disgrace to the music industry IMO - they need to make videos to attack each other and act like 12 year olds fighting in a playground.
Remember that MJ quote - "I have never attacked another fellow artist; great artists don't need to do that..." You need to therefore ask yourself, have MJ, Madonna and Prince ever attacked eachother or other artists with the similar status? I think you'll find that they haven't. Mariah Carey, Eminem, Britney Spears, JT, Kanye West on the other hand... Just goes to show how shite the world we live in is now. These people should be promoting peace, and show everyone that we are the world, but instead they have to attack one another which is so funny but disgraceful at the same time. The language used in Eminem's song "THE WARNING" is disgusting. I would sue him for using such language if I could. I can't believe Dr Dre wrote that song for him (stab at Mariah Carey if you didn't already know).
