Party Rap is bass-driven, block-rockin' hip-hop that only has one thing on its mind -- to keep the groove going. The lyrics are all inconsequential, with none of the political overtones of hardcore rap and only a fraction of the cleverness of old school rap. Instead, it's all about the music, with the bass and drums taking precedence. It's closely related to Miami bass music, but there is usually one vocal hook -- such as ""Da Dip"" or the chorus of ""Rump Shaker"" -- that makes the record memorable.
