Lets face it:

Janet Jackson can't sing, she has a thin voice without character, Jimmy Jam and Terry Lewis made it appear 'bigger' then it was, but she simply doesnt matter.

Latoya Jackson was even worse, a total nobody.

Jermaine is a mediocre singer that is best to be ignored, nothing more.

The rest of the family? what rest? If they had something special to offer, i would remember, but I don't.

yeah, no.
