The comment you are replying to seems to be pointing out that Ed Sheeran himself, i.e. his own brain, is trained on the past work of Ed Sheeran. That's how I read it anyway.
Yes, that's what I understood and why I said that maybe the author just doesn't like Ed Sheeran's music.
Well, Ed Sheeran self-trained himself, including positive feed-back on past work, on his own work. So in a sense, he still beats a Sheeran-bot!
This no critique of Ed Sheerans work so, I actually do like his older albums. The last one didn't leave an impression so far to actually remember it.
I don’t listen to the radio/album versions of his songs since I think they are a bit dull, but I thought his Tiny Desk concert was great.
It seems pretty obvious to me that whoever wrote that sentence did not like the album and was trying ineffectively to communicate.
