This is it, the song that launched one of the most successful careers in music history. The power ballad, co-written by Mariah, was her first single from her debut album, Mariah Carey, and became her first number one hit. The 1990 release is considered by many Mariah fans to be her signature song, and, though she hasn't confirmed it officially, most fans think the song is about her spiritually, and her pre-fame struggles, rather than a romantic interest.

Sample lyrics:

"Treated me kind

Sweet destiny

Carried me through desperation

To the one that was waiting for me

It took so long

Still I believed

Somehow the one that I needed

Would find me eventually

I had a vision of love

And it was all that you’ve given to me."
