Progressive Metal is Progressive Metal. You dont redefine names based on bands you do and do not like. Also, you have just been etremely Neoglistic. Alternative Metal is basically the forepart of Nu Metal, before its name changed and before the new batch of bands that got high critical acclaim. I also suggest you read the article on what Nu Metal is, and what Alternative Rock is. Not all Nu Metal bands are out to make money, many Nu Metal bands have made no money, and im sure you wouldnt know any of them.
