Andrew Wowk gives a first-hand account, confirming that Pauly is worse than you thought. Here is a review of a 2013 set from inthemix.com.
“9:30pm – Pauly D saunters on stage. My faithful companion notes his headphones and laptop are encrusted with sequins that form an Italian flag. As a reality star who’s segued his career onto the decks, it’s no surprise that Pauly has critics who question both his talent and motive. Rather than prove them wrong by immediately getting down to business, Pauly begins his set by dropping catch-phrases from Jersey Shore.”
