When my friend first told me that someone had combined beats from The XX with The Notorious B.I.G. lyrics, I thought there was no way it could do justice to either artist. Well, I was wrong. Notorious XX was mixed and produced by San Francisco producer wait what and premiered in 2010. To no one’s surprise, the album has had over a million downloads in ten days. Whether you’re a fan of either artist or not, this mashup is worth the listen.
