Artist: Frank Ocean
Release Date: 2011

Frank Ocean's ubiquitous debut Nostalgia:Ultra garnered a cult following shortly after it's release. Almost immediately, Def Jam execs swooped in to make a profit by negotiating a deal to re-release the singles "Novacane" and "Swim Good"--part of the reason why these songs aren't easy to find for free. Nevertheless, this mixtape shaped 2011 in a way that no other mixtape could and is very necessary for anyone who can respect the fact that all good R&B doesn't have to sound like Jodeci.
