Reply to Alexander Kowalski - Lock Me Up <-~ Why does this track sound like shit?

My almost namesake (only 4 letters in our names are different, same length) Alexander Kowalski made this track like 8 years back.

Unlike his other productions it somehow sounds dull and really really bad, like a 128 kbps MP3. I even bought the vinyl but it is the same.

Does anyone know what went wrong with this track?
