I think the point Jackson is trying to make is that Nine Types of Light is always compared to Dear Science, and is therefore dismissed because critical opinion says it's less good. Similarly Helplessness Blues is always compared to Fleet Foxes, and most people agree that it's less good, but it doesn't suffer from the same level of dismissal that Nine Types of Light has suffered. The hype surrounding Dear Science was huge, but for some reason, Nine Types of Light seems to have passed by with no one noticing.

These results are great! The only one in the top 10 that I haven't heard properly is M83, but they verge on the annoying to me.
