I agree with OP to some extent, these days he does seem more focused about being technical/rapping fast/fitting in as many multis as possible without really saying anything. He kind of reminds me of a football player past his prime (growing up watching Ladainian Tomlinson and his decline from 2008-2011 - he showed some bounce back in 2011 before completely falling off - makes me realize this I suppose) - Em still has some skill and ability, but not like early on his career. Using my analogy - he still shows some flashes here and there, but on the whole he just isn't what he used to be. There were some flashes on the re-up, relapse, and very few songs on Recovery, along with freestyles here and there. But overall he just isn't making good music(that actually sounds pleasant to your ears)/albums anymore.
Although prior to his fall off, Eminem made plenty of good music
