My definition of good, in this case at least, is somewhere between acceptable quality and typical "demo" quality. My point is that if the song is there and the performance is good you can get "adequate" results by just setting everything up and playing without worrying about the sound too much. I'd say most of my early recordings were worse than this with better equipment because I focused more on the gear than the music. Maybe you think it sounds terrible but I was very impressed with the tracks considering it's literally his first ever attempt.
And I wouldn't ever compare this to a commercial studio project in a million years, it's just something a musician did in his own home with absolute minimal gear and expertise.
