Downloading

Most people say that downloading music/movies from internet is their favourite activity, and it shouldn't be illegal, and I'm one of them.
Well, sharing is one of the things that are taught to us in the early times of our childhoods, right? When we download music or videos, doesn't it mean sharing what we have with the people who doesn't have opportunity to buy those things? So, what's wrong with it? The people that are against to the idea of free downloading say that it should be illegal as it is violation to the rights of the artists' and singers'. They say that by downloading, in a way, we are stealing the singers' and artists' money. But i don't think that it's correct. I mean are they really in need of that money? Can't they live without the money that they will have from a couple of downloadings? Or is it just that they can't live without the island or villa that they'll buy with that money?
In conclusion, I think downloading doesn't harm anyone and it is not a violation to any kind of rights. So it should be legal.
