If you though the DJ at Triumph was bad then avoid Harvest Moon any weekend night like the plague. It turns into an annoyingly loud and crowded "club" after 10...and personally, with a rare exception here and there, the beer isn't anything special...you'd be better off getting some decent craft brews at Old Bay, though that can get equally annoying on weekend nights. Live music most of the time though, but loud as hell for such a small bar area...
EDIT: After re-reading your post it seems you were already at Harvest Moon experiencing what I described above. Airborneguy is right. Being right down the road from Rutgers it caters to the college kids on the weekends. They have to up their level of *****ey-ness to compete with Easton Avenue bars...
