2-Too broad a term to really paint a picture of but is characterized by electronics, emotion, a tendancy to piss off a hypocritical self (and wrongly) proclaimed "true" metalhead (who should listen to some fucking Tool and Alice in Chains if he wants to know which talented bands to compare nu metal bands to in order to show how untalented they are), and less talent than the metal of the late 80s and early 90s. Sure nu metal bands lack solos and tend to write most of their songs in the same key and don't do anything that's technically amazing, but they have more emotion than all every "true" metalhead's bands combined! The downside to Nu Metal
3-Unfortunately a genre that appeals to teenagers who think they're depressed but are just too dumb to look around themselves and see that everyone else is going through the same thing, really haven't heard any real real real music and listen to bands because of the lyrics that are simple and dark enough for them to relate to and the image of the band. It's because of these dumbasses that everyone else hates nu metal.
Sure, Nu Metal bands aren't nearly as talented as 90's metal bands, but they're a helluva lot more emotional and interesting than emo and screamo bands
Nu Metal is closely related to rapcore.
Look at the "broken love"/other themes ratio of most genres. For pop, it's 90/10, for example, 80/20 goes for emo, hip-hop has almost no love, but that's another thing. You see, nu-metal DOES have love songs, but they are different from the masses, and the ratio is something like 40/60.
And why should people blame nu-metal for being mainstream-friendly? Why, in fact, is being "mainstream-freindly" bad? The mainstream is what most people currently like, and, even when its fashion goes away, there would people still listening to it.
And, who cares what kind of people are the musicians? Probably most famous classic music composers were mean bastards, but their music is still remembered. The Beatles were dope-heads, but they still are great. Understand it, nobody cares if Fred Durst is a poser. If you like LB, you like it. And if you don't, you don't.
So stop f***ing around and don't forget that music is made for people to have fun, not to argue. K?
