Okay, man, I've seen a bunch of your stuff on here and I've even seen you complain about how difficult the NG community is to please. Now, I don't claim to be any kind of expert on NG, but the problem, for me, is the same problem as the one that's been in all of the cartoons of yours I've seen, and please don't be offended: It's not really funny.
I mean, ok, let's do a breakdown of this cartoon: it's a parody of "party rock," only you're making a dick joke. What, from a humor standpoint, are you adding? What, in short, is supposed to be funny? Think about other parody songs, like Weird Al (because really, is there anyone else?). Can you think of a single one of his that doesn't have a plot? I can't. Honestly. Because a one note joke is, well... a one note joke.
Of course, that doesn't really solve your problem, but maybe it implies how humor should work. And thus far, beneath decent animation, you haven't really ironed the kinks out of that yet.
