If they push the price up, it's less convenient, less people buy, more people steal. The only reason people pay for those is because that .99 looks so cheap, like a real deal. They may not be greedy, music is one of those things that are hard to put a price on, but they are definetly "stupid" on some degree. They don't have a lot of bargaining power or room to make demands anymore. The more they push their luck the more people find other means. What they should be doing is thanking apple and the others for the money they brought in, as opposed to what would have been some of those customers would have bought the album in stores, and most would just use p2p or likewise.
Either some means of equal ground is going to have to be established, or one side is going to break. My vote would be on the music industry cracking.
Besides things like that, some cd's sell for 8 bucks give or take at places like circuit city and target. That is LESS than 99 cents a song, so it's never perfect. But it's hard to say what is right and wrong or good and bad. Sure stealing music is wrong, but it's so common place people don't even think about it really. However, looking back at how economy works, the customers usually hold more power than the sellers. (If only gas prices worked like this)
