Sure you do. There are plenty of artists and producers who go south after awhile...it happens quite frequently in fact...
Well, that depends. Are you talking just context? If that is the case, most people are always gonna like his "horrorcore" theme shit from the SODS and Loaded days. I like that shit, too, but Lynch has evolved past all that kiddie shit and is on a whole other level. LBI, lyrically, is his best work album wise...but the beats were "meh" at best. If he had the production level he got from Loaded for that album, would have been an instant classic. His rhyme pattern, his metaphors, and the way he put his words together are far superior to Loaded...not even CLOSE. The problem is, people only want to hear his shock value or how fast he spits...that is only ONE aspect of his capabilities.
Maybe yo need to go back and really LISTEN to his newer shit.
All great songs, but lyrically, they dont hold a candle to his to-date shit.
