I guess that's the case. It's not that I haven't tried more modern Hip-hop, I have lots of times but I just feel they lack these melodic, R&B-like qualities of the 90's and early 00's.
Rap these days is either A) A little too much auto-tune (Drake balances on a fine line here) or B) Trying to be "Old school" by trying to replicate more classics such as Illmatic in style. I'm pegging Kendrick Lamar in the latter category, but it's just not the same.
