It's actually simple to understand what happened
It was a pure transition from darkness of LSV1 and 2093 to brightness and hopefulness in 3093, ADLV1 and the feeling of being alive in LSV2. His sound, themes, lyrics were nice and diverse. He still felt like himself and became more sober after 2093, as he said in the interview. He's been "sober" (never fully) since 2024, not damn 2025 or 2026 or whatever.
His music was good not because of drugs, but because he stayed distant from allat mainstream bs. He was just passionate about his craft and mostly did everything alone. 2093 didn't make him wipe his persona tf down, idk what happened after. He prolly got a taste of life and started caring less about the music, thinking that everything he makes still hits the same. Everything bout Yeat's music now is connected with that "big game/worldwide fame" bollocks. Yeat is a brand now. That's the reason why it's worse than before.
He shouldn't'v scrapped ANY of his projects. 2023-2024 period was truly goated; (everything people complain about in LSV2 comes down to bad tracklist execution)
Dangerous Summer is still good though and potential ADL of the first half of 2025 could be too.
