I don't see anything at  that suggests 622,921th in Amazon's sales ranking makes them notable. It mentions (#4) that a band is usually notable if they have a chart success in a national chart but that would be a top 30, top 40, top 100 sales position depending on the chart. I've formatted your comments too to make them stand out better
