Mariah Carey was the most successful recording artist of the 1990s partly due to her five octave vocal range, partly to the fact that she is an excellent songwriter (she has been at least co-authoer on almost all of the songs she has released and as some rather unkind people have remarked, partly because she was married to the head of a major record label, Tommy Mottola.
One rather amusing episode was after her album for EMI had flopped (actually, not a bad album, but she was both physically and emotionally ill and could not promote it properly) they released her from her contract. Then paid her $28 million to go away. Great job if you can get it, right?
Her official website is here.
A couple of Mariah Carey fan sites are here and here.
The Wikipedia entry gives a good pooted biography andhas links to her albums and lyrics.
