"Round and Round" by Ariel Pink's Haunted Graffiti

The musical facts that I noticed in this song somewhat influenced my opinion. One musical fact that I pointed out was that "the vocals mumbled", and in my opinion I included that "I didn't like it because the vocals weren't understandable." I also pointed out that "the music is repetitive", and in my opinion I stated that "It wasn't very entertaining." There is a correlation between the facts I picked out and my opinion. Also, the facts that I picked out seem to mostly be things that I did not like about the song. I do have a listener's bias. The main one is that I think vocals of songs should be clear, and if they're not, there is a 99% chance that I won't like the song, even if it is really a good song.
