Reason #3: People want to hear more of Nicki spitting after hearing her most recent raps.
One of the reasons Nicki has enjoyed a nice run as of late is that, while she's done a decent amount of guest verses over the last year, she hasn't done so many that people are tired of her. There is still a really healthy demand for her music. And if you give people a verse, they will listen. From there, it's up to you to wow them with whatever you're coming with (like Lil Herb did) but Nicki will help you get people to press play on your new song.
