In the first example guitars sound very lively, like I'm actually listening to someone playing live. Very warm and cosy feeling. 2026 version is just some standard over-produced pop-music, that I would have completely ignored if I heard it "in the wild".
In the second example, 2003 vocal performance might be not perfect from a technique perspective, but I can hear real emotion in his voice. 2026 version sounds very bland, just like every other song that I might here on a pop-radio.
I want to say that I am not an anti-AI fanatic, I am generally curious about new ways to use technology (including gen-AI, but not limited to it) to create art. So I am not coming from "it's AI, therefore it's bad" perspective. I genuinely tried to listen with open mind and hear the music without thinking too much about how exactly it was created.
