This is all assuming that availability is the top priority for all artists. I think spotify has shown 99.999% of artists that their model of maximum availability at all costs simply doesn't work, either in terms of contacting an audience, making any money or valuing music. It just results in the vast majority of artists being insulted and demoralised and the remainder producing music of a relentlessly narrowing artistic scope. Are you more likely to get around 3500 plays on spotify or get £1 in donations off the back of giving your music away for free? It sounds absurd and that's because it is. Most artists will get the same out having their music on spotify for a year as walking out onto the street with an acoustic guitar for half an hour on a Saturday. At least out on the street you're not propping up a capitalist giant and a tiny 'elite' of ultra commercial music producers. For me spotify and it's ilk have been the final nail in the coffin for integrity and reward in releasing music and I would encourage the 99.999% to boycott it and forge ahead with alternatives. Nothing better will emerge until then and artistic culture will continue to become more and more bleak.
