Party Rock Anthem was released by LMFAO in 2011 and became a huge dance hit built around its party rock hook and heavy electronic drop. The muffled edit follows a popular online format where familiar songs are filtered to sound like they are playing behind a closed door or in the next room. That version spread through meme videos and soundboards because the joke needs no explanation, and the recognisable melody still works even when the bass and vocals are dulled down to a distant thump.
