Query: WOW! Christina IS the BEST!

What can I say? Christina can sing virtually anything. I think its great that she's exploring her Latino roots through her first Spanish Language CD. She really nailed the language. In the world of teen pop non-singers (Britney Spears) Christina has proven time and time again that she will be the one left standing after 20 years has gone by. Christina Aguilera is like the next Mariah Carey or Whitney Houston. Go BUY this CD, Ill gurentee you that you will not regret it!
