I've made more money busking with an acoustic guitar on a busy corner in 2 hours than I've made from streaming. This is how I use Spotify - it's a street corner that pays in pennies. However, I can't afford to travel the world to get in front of people. Thus, while it's very close to the "exposure" concept of compensation, at least there's an exchange of monies as a matter of principle.
There's a German metal/rock band called Unheilig that I heard about in 2013. After seeing a YouTube clip [1], Spotify / Rdio let me try more of their songs & add them to my playlists. That hooked me enough to add the album to my Spotify offline downloads so I can listen on the train.
At that point, I'm a committed fan who doesn't want to lose the album... so that's when I buy the CD. Two years later, I've bought all their albums, 2 limited Super Deluxe editions, t-shirts & hats & merch, and been to two of their concerts. Unheilig probably got nearly nothing from me via Spotify, but it was an important step in getting me hooked & ultimately spending hundreds of dollars.
I'll admit that Napster, to me, was an avenue to find things that I couldn't get my hands on otherwise. My favorite search term was "remix" and I got unreleased / international tracks that I still love to this day. I'm a consistent Beatport Pro customer, about $20 a month, and I buy physical CDs for artists to both help their traditional sales metrics and simply for nostalgia. I can't tell you how happy I was to buy the last Columbia release by Weird Al and be a part of giving him his first #1 album release of his career. Yeah, it's kind of hokey, but that's what's so fun about music - from cradle to grave, there's no shame in loving what we love.
It's either make something, embrace the income potential, and keep creating, or whine with whisky an die in the gutter, figuratively speaking.
Look, my perspective is that music is supposed to be made for two reasons: 1. the personal compulsion to create something that reflects the individual, and 2. sharing those products with a limited expectation of fiscal reward. This is not to downplay the desire to make a living from art, but an informed historical perspective doesn't infer that technology and modern business has changed the nature of the relationship between artists and consumers very much.
