Chumps don’t think I can flow
So here we go, release a new track to show the wack
That I can throw styles back and forth, fast and slow

He released this track (and probably other records) to show all of his doubters & weak MCs he can flow and is versatile. He wants to show them that he can use many different styles in his songs.
