Bands doesn't really earn money through record sales, but in large by concerts and merchandise. Those only have a limited amount and you can't copy those.
Here's an example:
For one night playing at the Quart festival in Norway, the festival offered Metallice 10 million NOK (rough estimate 1,8 million US $). The festival already have it's own advertising, light show, sound system and appropiate people to work them. Only thing Metallica has to do is to drag themselves, their equipment and their technicians to Norway to play for 2 hours. That is for a concert where absolute max capacity is 50000 people. That means that each person is paying 38 dollars to see Metallica live.
Roughly estimated, that's 2 full albums. Or, if you say that the artist earns 20% of the sales (which is quite alot), we're talking about 10 albums worth of sales.
They get that from 2 hours of playing. And not to mention merchandise they sell there.
For the record, Metallica turned down the offer.
Now, this is an extreme example of how much money is involved in concerts. Lesser artists earn less because they have smaller concerts, but for the really small bands, we're talking about 5-20$ in tickets, where almost all go to them. They would benefit greatly from getting their music distrubuted alot more, so more would come to their concerts. As you can see, they earn more per person visiting ONE concert or buying ONE piece of clothing than selling one CD.
Studios doesn't cost that much. Yes, they are expensive, but the equipment-frenzy has gone wild. A good band doesn't need to pay their asses off to get a good record. We are talking about really good equipment that records music for 44,1kHz/16bit? That's what I call a waste of money.
So, I have no sympathy for the MUSIC i download, but movies and TV-series, I see bigger problems in.
Edit: My bf wrote this while I was at school. I mostly agree with him though.. Except for TVshows - I don't pay to watch them on TV so I don't feel bad dl them for free either.. + we live in Norway so it's a must to dl if I want new episodes. And I also buy CD's if there's a band I like
