I know he had 23 and that miley song, but you aren't looking at the time lag of production. Those songs were likely made in 2012 and put out in 2013 but where's he at on all the releases you'd expect to see him on? like I said Jay z rejected him and he couldn't bring a hit for 2chainz. Pay attention, nuthugger, lol.
And more recently he's had 2 singles with Future not crack the top 100. For a guy with his skills and a big production team, wouldn't you expect a constant stream of hits? Mustard has 3 songs in the top 50 right now.
