Are independent bands surprised that they make little to no money whatsoever through streaming? The pay from a single stream is a fraction of a penny. Unless you're getting millions of streams, you're not going to make money from it. I don't think it's as unfair as some people make it out to be. The bigger artists get the same amount of money per stream, but they benefit from getting millions more streams than some independent punk band who release their own 7" singles. I know a number of bands personally who willingly have their music on Spotify, knowing full well the money they get from it is literally pennies, but it's about having the music there for people to discover, and having the music on Spotify has been of an enormous benefit to them.
A friend of mine runs an indie record label, and he and his bands make no more than a few quid per quarter in total (to share out between the bands he has released records by) from Spotify plays. But his direct sales for CDs, LPs and merch have dramatically increased since putting the material on to Spotify. Prior to Spotify, he was losing money on releases. Since Spotify, he's breaking even on them. He actively encourages all his bands to have their music put on to Spotify, even though the return doesn't come from Spotify directly. It comes from people liking the record and buying a physical copy of it, plus merch, going to a show, and whatever else. Independent music has worked in a similar way for a long time, going all the way back to home taping and tape trading and buying the music you discover through it to support the bands.
Independent music was built almost entirely on exposure. Even the first incarnation of Napster had an incredible effect on the independent music industry in terms of people discovering music and then buying that music legitimately. An enormous amount of indie artists were in support of Napster (and even bands as big as Radiohead, The Offspring, Weezer and Public Enemy), even though they made no money from the music being shared. It was the Metallicas and the Madonnas who had a problem with it. The exposure to the music was the bigger picture for independent bands, and a lot of people tend to buy music they like upon discovering it, or they'll go see the band when they tour, buy a shirt etc. A point which Lars Ulrich seemed to miss the first time around. Spotify is obviously more legitimate, and it cuts out the piracy element of it, but the ethos behind the use of it for an independent artist is very similar, having music readily available for people to find, share and discover.
Bands will make very little money from selling/streaming music anyway, even bigger bands. Major artists will always get the bigger slice of the pie, whether it's radio plays, streams on Spotify or getting your CD on the shelves at HMV. As an independent artist especially, with the cost of even producing a record, you're very fortunate if you even break even from writing, recording and releasing a record, as the whole process can cost thousands (and thousands!) to put together. If indie bands aren't happy with the treatment they get from Spotify, then it's easy enough to pull your catalogue from it, or not use it at all in the first place, but what is the alternative for an independent artist? They could put it on Bandcamp and charge whatever they want for downloads (but get absolutely zero for streams), though Bandcamp receives a fraction of traffic that Spotify gets.
Either way, unless you've got a promotional juggernaut behind you in the way of a record company, little money is to be made from recorded music. Nobody wants to pay for mp3s because they are so disposable, and whilst vinyl sales are the highest they've been in decades, it's still considered a niche market. So get in a van, go on tour and merchandise the crap out of your band. You think Glenn Danzig got rich by deciding which high-fidelity online streaming platform to go with? No, it was probably because he put the Misfits logo on anything big enough to print a Misfits logo on to.
