oh right lol
nah they don't you're right. Was Cube's Death Certificate sonically ground-breaking? Far from, but classic album. But it needs to be somewhat respectable or maybe have purpose. I don't think Nas knows how to pick beats that fit the album, that give it a sort of focus or overarching vibe.
Also, just because Nas is rapping great nearly overtime doesn't guarantee the album will be classic. The album has to be relevant, it has to have some sort of direction, not just a collection of tracks etc. There are a few things that go into it. Nobody's questioning Nas' lyrical ability.
Why isn't Inspectah Deck's debut album a classic?
To that point though, for the most part I dont his think beat picking abilities is that bad through the history of his career and I think it was more an issue in the mid 2000s than it was before that where although he wasn't picking those golden era producers of like Pete Rock, he was picking producers of the time to run with and people really didnt complain about that (The issue back then you recall was "Why is he being Escobar or crossing over"?) The beats he picked where kinda what NY rappers were doing (Swizz, Hitmen, Trackmasters, Timbaland but then Premier and LES etc).
He settled a bit post Stillmatic to lesser known producers but I think the combination of star producers in Hip Hop being more of a importance again (Thanks to Blueprint, Black Album) and the release of God's Stepson by 9th Wonder had people taking that narrative on him and it really became noticable on HHID and Untitled (Streets Disciple I didnt think had a beats issue as much as a 2 CD filler issue)
But since Life is Good and the combination of having No ID (Who is way more diverse than people give him credit for), Salaam (who was always the only guy giving him good beats post Stillmatic and sometimes baring the brunt of the other producers giving wack beats and people assuming that was him too) and Anthony Saleh as his manager giving a more contemporary focused opinon that reflects what his fans want, I kinda feel like he kinda resolved that a bit on this last album. Be interesting to see where if he stays that way on the next one.
But its funny you mention his bad beats being a cause of no direction, because weirdly enough I feel like his most schizophrenic beat albums actually have a direction and theme overall but its just people felt they could have been other guys they wanted to hear over the ones he choose.
