I have developed a scale that can be used to describe most guitar based music:
It has four components.
Style: (0-20), where 0 is folk/country, 5 is folk-rock, 10 is rock and 20 is heavy-satanic-fantasy-death-metal
Mood: (0-10), where 0 is kill-me-now-depressive, 2 is Coldplay, and 10 is lets-jump-up-and-down-like-idiots-on-speed
Originality: (0-10), where 0 is yet-more-coldplay/arctic monkeys, and 10 is Eberg.
Popularity: (0-10), where 0 is the band at your local, and 10 is the beatles.
Discuss.
