Firstly, 'none' is not a contraction for 'not one'. It is a DESCENDANT of a contraction for the Old English phrase meaning 'not one'.

Secondly, the usage of the word depends on what you're talking about. 'None' is defined as both 'not any' (which is the first defintion, mind you) and 'not one' on m-w.com (dictionary.com is down -_-). In the case of 'not any' (i.e., 'not any amount' of something), you would usually use the word as a plural. In the case of 'not one' (i.e., 'not a single one' of something), you would use it as a singular.

What can ya say? The RIAA wants to make a point and they've made a point; they target people that abuse the least but do it the sloppiest. We all know what that means!
