Rating System:

0.5: Irredeemably bad.
1.0: An incredibly poor showing, albeit with one or two notable spots.
1.5: Bad, with some salvageable material.
2.0: Slightly below average.
2.5: Average.
3.0: Slightly above average; good.
3.5: Great.
4.0: Excellent; very few flaws - which are often part of the record's charm.
4.5: Wonderful; a rarity for its top-to-bottom quality.
5.0: A peak.

2.0-3.5s are generally recommended, with some sort of reservations built-in; 4.0s and above are heartily recommended with few (if any) qualms.
