Query: Even the best producers couldn't save her terrible voice!

I love earlier J.Lo materials either with stronger dance beats or when she sounded like Mariah Carey's Hip-Hop songs(like her "I'm Real" remix which was inspired by Mariah Carey's "If We"). Since my friends pointed out that most of the catchy chorus in her songs was actually sung by background singers, NOT J.Lo, I really was not sure if I bought a J.Lo album or her backup's album. In Rebirth, I think "Get Right" and "Cherry Pie" are the only two listenable songs in this CD.
