I'm going to give my answers from 2012...
How many albums did I buy in 2012?
One. The 2nd Law, by Muse.
What do you do when you can't afford to buy music? Pirate it or just don't listen to it?
I listened to Flying Colors on Spotify, an ad-funded legal streaming service. Extensively. Additionally, friend sent me Les Fleurs du Mal, by Therion, which I listened to once. The same friend also sent me Epicloud, by Devin Townsend, which I haven't listened to at all. This is my entire year in music.
Do you download to sample the music, before you buy?
No, I download if someone else wants me to sample the music before I buy.
Do you prefer digital or physical media?
I prefer physical media, but it's not a luxury I can really afford. I'll buy bits and pieces in digital whenever necessary.
Does it matter to you if it's an established "rich" band, or a struggling, lesser known artist?
Again, I don't really have the luxury to discriminate. My main priority is buying for me. On top of that, I will have fewer qualms downloading from an artist who's on the record as being cool with it (say, Devin Townsend) than an artist who's not. That said, I don't think not hearing a record is going to make me any more likely to find money to spend on it, so while I mostly make do without, it's not like I'm staying awake at night thinking, "I hope Therion doesn't mind."
What about albums you only "sorta" like? Do you buy them anyway?
I don't buy albums I really, really like - "sorta" never got a look in. Downloads aren't my way of discovering new bands, the only time I download something is if a friend wants to show one to me. Copyright law states that it's not really theirs to show, which is fair, but at the same time, the worst case scenario is that I listen to it and then carry on with my life. I'm not buying less music because it's being sent direct to my hard drive.
The music industry is fuelled by free samples, though. Musicians dream of radio play, corporations used to illegally bribe radio stations into playing their artists' songs, because the only way anyone finds out they like a band is by listening to that band. Does that justify a world where everyone downloads music by the gallon? I don't think so. And can the public be trusted to pirate responsibly? Not really. But when you asked about whether it matters to me whether the artist's rich or poor, I think that piracy's most noble outcome is that of a universal equaliser.
Because it levels the playing field. Hungarian Folk-Metal Band #143's audiences wouldn't suddenly become any bigger if file-sharing was obliterated. And even if someone who pirates a CD never buys that CD - the worst case scenario, as I said, is that they listen to it once and move on, but if they grow to like the band, they will find ways to talk about it.
Humans are social animals, and a music fan will discuss a band they like, and namedrop it, and recommend it, and bore their friends' tits off, and they will often become part of a chain. And in that way, the information travels across the world. Some people will download it, and those people will tell friends and even more people will download it, and as the music spiders its way across the surface of the planet, the chance that someone is finally going to decide they have to buy the album only gets greater. These aren't people who would've otherwise looked at the CD cover and gone "Yes, let's buy the discography." Very few of them would've seen the CD cover at all, not living in the Hungarian village of Blockelsplatt where Folk-Metal Band #143 do all their gigs. They are, perhaps, people who could just as well have streamed the album over Spotify, downloaded the sampler from the band's official website, people who've been a little greedy - but every time someone in Spain, Canada, Puerto Rico logs onto Amazon and buys Hungarian Folk-Metal Band #143's new album, I don't think that's twenty-three potential sales lost, I think that's a sale gained, and one that could never have happened before the information age.
