I'm Elijah. I really like music a lot. Here's my rating key or whatever.

5.0=amazing, perfect
4.5=really awesome, almost perfect
4.0=really good
3.5=pretty good
3.0=ok
2.5=pretty bad
2.0=very bad
1.5=pretty awful
1.0=awful
0.5=incredibly awful

I also do ratings on a scale of 1-10, 10 being the best and 1 being the worst. The only ones you'll see on any list will be either 9, 9.5, or 10:

10=perfect, or 99.5% perfect if it also has a 4.5 star rating
9.5=almost perfect
9=pretty darn good
