EDIT: Let me elaborate in regards to ehnto's argument. DVDs, clothing and cars are all physical items I am paying for and therefore I am happy to pay for that. I am also happy to pay to see a movie because movies could not exist prior to being able to film. Movies are the end product that I want to see.
All of these are different to music. Music existed well before the ability to record it did. All that recording did was make it more accessible. Back when you had to purchase a record or CD there was a physical item you ended up with to listen to that music. Therefore something that was worth paying for. I bought a lot of CDs. The music is not the end product. The live show where I go to see the musician perform is.
I don't get paid for people to use my work without any involvement from me past the fact I created something. Why should a musician be paid for you listening to the music they created. They aren't putting in any hours for me to hear that past the original creation. What are they getting paid for?
This is why I love artists like Hoodie Allen and Chance the Rapper. They release the majority of their music for free. Hoodie Allen was unable to release one of his albums for free on iTunes, so he charged the minimum. He was constantly on social media telling people they can download his album for free from multiple locations and that they didn't have to buy it on iTunes. People still paid for that album like crazy.
On that note... fuck the music industry.
