Drake is taking his Aaliyah obsession to a new level. Last year, he got a tattoo of the late R&B great. This year, he's releasing music with her. The Toronto rapper is reportedly set to executive-produce a posthumous Aaliyah album featuring unreleased recordings made before her 2001 death in a plane crash. The first single from the project, "Enough Said," hit the Web over the weekend. For better or for worse, this is just the latest "duet" between living and dead artists. Click on for a look at other notable posthumous collabos.
