Seriously, I was searching about her discography a couple days ago and I can't remember a single by her that didn't get a video or at least a performance at some point. Even flops like Hold It, Don't Drop It, Fresh Out the Oven and Louboutins. Is Google Images ICON Jennifer Lopez the original Promo Queen??
Maybe lately, but not in the beginning of her music career. I don't remember heavy promo Waiting for Tonight, Love Don't Cost a Thing, I'm Real, Ain't It Funny, Jenny from the Block or All I Have. I guess it wasn't necessary then.
