Unlike the classic debate over 2Pac or Notorious B.I.G. being the greatest MC ever, both Lil Wayne and Eminem are still very much in the game and cranking out hits, with each artist sitting on discographies of over 1000 tracks.
The themes of the album (family talk, personal problems, fighting to win) stick to the traditional Slim Shady formula, but Em is no longer the hungry and provocative MC he once was -- he's one of the most successful musicians of all time. His success hasn't done him any favors.
When I thought hip hop was becoming a more accepting place with Frank Ocean coming out as bi-sexual, Macklemore and Ryan Lewis releasing 'Same Love' and both becoming commercially successful. 'Rap God' was just a gunshot taking us back in time making us realise that we've got a long way to go.
In a year when some the rap's heavyweights pushed their craft either creatively (in the case of Kanye West's innovative Yeezus), or by breaking new marketing ground (such as Jay Z's Magna Carta...Holy Grail) the smaller scale ambitions of Eminem seem quaint by comparison.
I wrote to Sia on Twitter and expressed my disappointment. I wasn't expecting a reply, but, to my surprise, she responded and thoughtfully listened, and we proceeded to have a lengthy (by Twitter standards) conversation.
In recent years, I've grown tired of hearing people who would classify themselves as music lovers offering vaguely snide comments about rap and Hip hop artists making the grade in the Rock & Roll Hall of Fame.
