Why do people think all this music is Free?
Sure, musicians are being screwed over by the labels and publishers, but that's not a reason to outright steal it and deny the musicians the meager cash they are getting paid.
In the past, free (stolen) music was not common - relatively speaking - because the means of distribution were limited. The average consumer of music understood that the form factor - record, 8 track, tape, CD - required they buy it once. This set the bar for musicians (though let's be honest, record companies always made the lion share of the profit) to expect they could sell their music at a certain price.
Fast forward to our hyper-connected world, delivery seems effortless, or at least bundled with the monthly fee we pay our ISP. Stealing music no longer feels like actual stealing because it is all digital, and we're accustomed to sending and receiving bits without a thought to the huge amount of infrastructure and manpower required to create content and keep all those servers running. Additionally, the market forces dictate a new pricing structure because we're consuming music sans physical medium, so the expectation is that price will drop accordingly. But we have a decades old system predicated on the $10 - $15 price point (give or take inflation) for an album.
We have conflicting interests: Joe Musician still has to perfect his craft and write all those songs. He can engineer it at home, but let's be honest, that is often obvious in the end product. Either way, Joe still has the same level of effort to make an album, but the consumers now have the world at their fingertips and an expectation that with a widespread and immediate audience Joe will take a lot less for his record.
Note: This is not a new phenomenon, nor is it only in the digital space. Costco and Walmart have done the same thing for the cost of manufactured and farmed goods. Do those cheap chicken thighs really reflect the cost of raising chickens? They do if one is okay with cramming chickens into a factory farm. In this instance, the environment and well being of the animals suffer, so no one complains.
