Rapper's delight or weapons-grade nonsense? The app that uses AI to help MCs bust a rhyme

I may be many things, but I'm not a rapper. I discover this when I'm asked to freestyle a few verses on a visit to London's Abbey Road recording studios. Immediately lines from famous rappers flood into my head – some classic Biggie, a few Young Thug yelps, the theme to The Fresh Prince of Bel-Air – but I've got to think up something original. Out of desperation, I decide to rap about my morning routine. Adopting a slow pace and simple rhyme scheme that even the Sugarhill Gang would disdain, I begin: "I wake up at seven and I brush my teeth."
