This week (beg20Jul15), the Ima Boss hitmaker aimed a lengthy rant at the Best I Ever Had rapper on the microblogging site, urging fans not to compare him to the star since Drake reportedly uses a ghostwriter.

Superstar rapper Fiasco has now chimed in on the controversy by writing his own missive on Instagram.com on Thursday (23Jul15), and while he praised both artists, he defended ghostwriting, insisting it is "part of the art" of making music.

Accompanied by a photo of an animated ghost and the phrase "The Haunting", he wrote, "To rappers from a rapper... Simply write your own rhymes as much as you can if you are able. Ghostwriting, or borrowing lines, or taking suggestions from the room has always been in rap and will always be in rap. It is nothing to go crazy over or be offended about unless you are someone who postures him or herself on the importance of authenticity and tries to portray that quality to your fans or the public at large.

"Some of the most pivotal moments in rap have been ghostwritten verses... The art form is kept alive and progressive in the activities of the tens of thousands of rappers around the world who are everyday trying to think of that next witty bar... Meek Mill struck a nerve accusing Drake of having a ghostwriter and the entire rap world reacted on all sides of the fence because rap is alive. It's active and it feels. Its rules and traditions are vibrant and responsive. I enjoy both these brothers' music and find inspiration and appreciation from both of them... At the end of the day, for better or worse, rap is alive even if some of its greatest moments are written by ghosts."

Fiasco is not a stranger to ghostwriting - he reportedly penned a number of verses for Jay Z in the past.
