Yes i like Mariah Carey and her songs, full of meaning and she got an amazing voice. One of my favorites has to be the "fourth of July". but then i think she sings all the same kinda songs, tune..etc.
Christina Aguilera... her songs have so much meaning to them and they can get you through some rough times if you just sit back, relax and listen. Shes a amazing singer and her album 'Stripped' is just too good!
