I'm a massive Hip-Hop/Rap music lover. I love Kendrick Lamar (found him 2 years back when hardly anyone knew him
), Meek Mill, Kid Cudi, Game, 50 Cent, A$AP Rocky, Tech N9ne, Big K.R.I.T, Chamillionaire, Kanye West, Big Boi and my guilty pleasure of Chief Keef
.... Thats just to name a few.
BUT the question is too subjective... So based on NOW, I would have to say Kendrick Lamar is at the top at the moment, as he is featured on nearly all albums I've picked up this year and the near future.
