The Mohs scale of hardness determines how hard a mineral is. With some modification (even the hardest metal bands don't scratch glass, one of the tests from the actual scale), this system can be modified to apply to musical hardness. The 'scapist only allows 8 poll options, so I had to squish the scale slightly to fit, because it's out of 11.
The scale only really works for rock and metal though, so keep that in mind.
The list can be found here, for additional examples and more detailed summaries. [http://tvtropes.org/pmwiki/pmwiki.php/Main/MohsScaleOfRockAndMetalHardness]
Examples:
If you have any issues with the examples (eg, "You dolt, your example of a three is harder than of a six!") let me know.
I mostly prefer seven or eight, although I like the occasional nine. Past that there's just too much growling and screaming.
EDIT: I changed eleven, The Sanity Assassin [http://www.escapistmagazine.com/profiles/view/TheSanityAssassin] provided a better example.
EDIT 2: Here's a section for techno music, courtesy of Distorted Stu. [http://www.escapistmagazine.com/profiles/view/Distorted%20Stu]
It's advised to skip to the middle or so of the techno songs, as they have dull intros.
EDIT 3: Novskij [http://www.escapistmagazine.com/profiles/view/Novskij] gave me a better example of a ten.
