Too simple.
Its alright, sorta funny.
It's just the only thing you've done, it terms of good animation, is lip-sync Dave to the song, to a plain background.
Why watch what I can listen to in the audio portal.
Word of advice, if you're gonna make a series of these, add some hooks and things to keep it interesting and funny. Build on the joke the song has already given you.
Something could be, animating the background singers and in this particular songs case, you could've had 'happy Dave' killing himself in numerous ways.
Hope I've helped you to make a successful series,
