I actually don't see the "growth" that you're speaking of.
2014 Forest Hills Drive is overall his deepest conscious album, no fluff or singles, and all that... yet, to me, his earlier albums had his best conscious songs on them then what I'm hearing on this album.
Lights Please
Rich nikkaz
Runaway
Lost Ones
Breakdown
Are superior to the songs on his latest album. I don't think he's really growing much as a lyricist. He's been able to improve his focus throughout an album, I'll give him that. But after a week of having this album, I'm already feeling like there's not much to go back to. And it's not that it's a bad album, it's just coming off as one of those albums that I have to be in a mood to play. The songs in general all are in a similar vein, and kind of blend into each other towards the end.
It's like as a whole, yes, it's better quality overall. Not any horrible songs, but there aren't any standout songs on here like his previous albums.
EDIT: He also has plenty songs from Yours Truly that could easily be listed with the songs above too.
