don't know if this like common knowledge but found this rap song from 2011 called "last day alive" by daniel jordan that uses the same instrumental as daytona meth/hollywood movie/party girl

thought it was kinda cool, i wonder if she got the instrumental from a royalty free beats website or something since this song doesn't have any producer credits either. maybe then the other laptop demos that we don't know the producers of have their instrumentals floating around somewhere online
