Dang.. I'm almost 60 years old, never worked in the music industry in any capacity whatsoever, but I guarantee you that if somebody laid down a beat for me, and gave me a little time, like an hour or two, to come up with a concept and write some lyrics, I could Mumble rap my way to the top of the Mumble rap chart.. if such a chart even exists.
I mean, Limp Bizkit at least was how rap metal should at least sound like. This was just a few guitar strums accompanied by a "goo", followed by another shitty hiphop/rap "song".
