To the OP -- yeah, that is a lot of money to pay for music.[/QUOTE]
Unless you're one of the top grossing acts (i.e. Metallica, U2, katy Perry etc...) you're not making much on a tour. And of course if you're not at that level you're also not selling shirts, bumper stickers, tour memorabilia, etc... Then, if you're at that level, your production cost on an album is so astronomically high that record sales aren't creating a huge profit either. Factor in the clowns that think music is free because it can be gotten so and you're honestly lucky if you get 2% return on the investment. Add in declining retail sales in general, the cost of shelf space, minute profit margin on big box sales, increasing tour costs and other such things and even the "top" artists make very little these days, compared to the good ol' days at least.
About the only way to get rich in the music biz these days is to be an incredibly in demand and talented producer.
We all know that Metallica are a bunch of millionaires, but think about how much time is spent in rehearsal, travelling, writing, recording, re-recording, doing press/interviews, showing up for non-concert events and you start to realize that they're making about $40 an hour.
Now take a lower tier band that's busting their ass on a self-financed tour to sell their CDs at shows for $10 (at a production cost of $9.50) and split that 4 ways amongst the band and you realize that they lose money hand over fist.
Then look at how the music industry works as a business model and discover that "the talent" is the lowest paid person in the whole enterprise outside of roadies (and they only do it for the pussy). The reason that you get overproduced garbage a la~ Bieber is because it sells to the demographic that isn't spending money on much of anything else. While payola may be illegal, it's there in spades outside of radio these days. Do you think the Yahoo! music site really finds that many interesting tidbits about a 17yo Canadian kid? Or is it that his label and his handlers want his name out there as much as possible to keep interest afloat?
Long story short, support the bands that you like by BUYING their product or watch them disappear more and more in favour of crappy bubble gum pop that will always sell no matter what.
