2 Chainz is calling out those artists who have developed a knack for remixing and redoing his songs. The idea of remixing and redoing songs has become a popular practice within the R&B/Hip Hop community. I don't know why 2 Chainz feels that he is so special though or that his songs can't be replicated. Maybe the new money and increased fame has made his head a little bigger.
On other hand I can understand what 2 Chainz is saying though. I used to always get annoyed with Trey Songz covered another artist's song. I always wondered why he couldn't do his own song but he had a trick up his sleeve. It was just his way of overexposing himself like he did before his album Ready came out. It was a tactic that worked though.
Usher has chosen Dive as the fourth single from his recently released album Looking 4 Myself. The song was produced by Jim Jonsin(worked with Trina) and Rico Love(produced It All Belongs To Me by Monica & Brandy).
