Listen to Jay Z on iHeartRadio

(Yahoo!) - More than 17 years after his debut album, you'd think we know all there is to know about Shawn "Jay Z" Carter. After all, the 43-year-old hip-hop mogul published a memoir entitled "Decoded" in 2010 and has opened up to Oprah Winfrey on more than one occasion.

But it looks like there is still plenty to learn about Jay Z. Here's the CliffsNotes version of the "Holy Grail" rapper's interview in the November issue of Vanity Fair:

1. Blue Ivy's as divided as the rest of us on whether or not she prefers music by Jay Z or Beyoncé.
Bey claims that Blue is a bigger fan of her dad, but he's not convinced. "That's not true," he tells the magazine. "She does like her mother's music — she watches [Beyoncé's concerts] on the computer every night. But my album came out and I don't know if Blue ever heard any of my music prior to this album — she's only 18 months old and I don't play my music around the house. But this album was new, so we played it. And she loves all the songs. She plays a song and she goes, 'More, Daddy, more … Daddy song.' She's my biggest fan. If no one bought the 'Magna Carta' [album], the fact that she loves it so much, it gives me the greatest joy. And that's not like a cliché. I'm really serious."

2. His past as a drug dealer taught him important lessons about business.
The entrepreneur says the time he learned much from the spent growing up in a rough Brooklyn neighborhood, where he says he sold but never used crack beginning at age 13. "I know about budgets. I was a drug dealer," he admits. "To be in a drug deal, you need to know what you can spend, what you need to re-up. Or if you want to start some sort of barbershop or car wash — those were the businesses back then. Things you can get in easily to get out of [that] life. At some point, you have to have an exit strategy, because your window is very small; you're going to get locked up or you're going to die."

3. Don't look for any Blue Ivy diaper bags anytime soon.
The mega-mogul parents earned an estimated $95 million between June 2012 and June 2013, according to Forbes, but Jay Z and Beyoncé have no plans to add to the family piggy bank with Blue Ivy merchandise. Although they filed to trademark the little lady's name, Jay says it was strictly a preventative measure. "People wanted to make products based on our child's name," he shares. "And you don’t want anybody trying to benefit off your baby's name. It wasn't for us to do anything; as you see, we haven't done anything."
