Whatever This Color Is = nope (one of the bottom 10 worst songs I've heard in my entire life)
Dark Orange = worst (so awful it's not even funny)
Light Orange = among the worst (reserved for when there's just so many songs that could be considered the worst)
Red = terrible (really bad, containing very few if any qualities to it that work well)
Light Blue = bad (fairly bad but at least a bit tolerable, mostly bad but with some redeemable qualities, or bad but in a way that's funny so I actually listen to it sometimes)
Yellow = mediocre (still not very good but I can think of multiple qualities that keep it from being worse)
Pink = decent (equal parts good and bad, or good but forgettable and not the type of song that I would ever think to listen to on my own)
Dark Blue = good (song that I like but could have been improved in one or more areas)
Green = great (a song that I would definitely listen to again, strongly created, and very few if any qualities to it that are weaker)
Light Purple = among the best (incredible song that is one of my personal favorites)
Dark Purple = best (so amazing it should be illegal)
Really Dark Purple = yep (one of the top 10 best songs I've heard in my entire life)
White = no opinion (either it's an album interlude and not a proper song, I haven't brought myself to listen to it yet, I'm completely undecided, or I have a reason for intentionally hiding my real opinion)
