My rating system:

<70:    Overwhelmingly flawed. Will not be rated.

70-79: Obvious flaws/bland but drinkable to varying degrees.

80-82: Evident quality but basic and uninspiring.

83-85: Daily Drams. Not special but of solid quality.

86-87: Good with little flaws which can be ignored.

88-89: Very good. Tiniest flaws/brief uninspiring moments prevent it from reaching greatness.

90:      Great and exciting. No appearent flaws. A few wow moments short of excellence.

91-92: Excellent. An ideal representation of the style. Said wow moments evident and abundant.

93-98: Legends of varying degrees.

99-100: Holy grails.
