I'm talking about you owning EVERYTHING they've ever produced. All the LPs, EPs, singles, remixes, alternate artwork, foreign editions, etc. I want to do so with a lot of artists but I'm very obsessive so I know that I'll probably end up selling my car if I do. It's very informative, however. For those of you who only buy the main albums in stores or on iTunes, you'd be surprised how much music you haven't heard from a lot of your favorite artists. I tried to be a Bjork completionist but it got to the point where I'd have to file for Chapter 11 just to get all her Japanese releases on eBay. Then there's also the realization that no matter how hard you try, you won't be able to own everything an artist has made because two new things pop up for every one that you buy. It's a very Quixotic or Sisyphean task. I doubt even ?uestlove owns every Prince release.
