I have friends and family in the music/entertainment industry. Some struggled for years and gave up, some are still struggling, some are very successful. I've seen them try everything from self-producing to kick starter/Spotify and even up to signing with major labels. So I sympathize with what you are saying, I really do.
But Spotify, Google, Apple, Atlantic...none of these companies are friends to the little guy. The little guy is never going to make decent money from a huge conglomerate/mega business. It's unfortunate, but true. The best thing the likes of Spotify etc. will do for the little guy is help them be discovered. Back in the day this was really only possible by playing at small venue locations and someone noticing you (or knowing someone in the business). So, yes, these new mediums *do help* but they won't make a small time artist a decent wage...just like playing at a semi-famous dive bar won't pay rent.
I very well may have it all wrong. I admit that. But the people I know that have signed with big record labels were not discovered on Spotify or Youtube. They got paid nearly nothing to play in semi-famous dive bars that have decent exposure. Most gave up, some are still trying, a few were "discovered" and signed.
So what is your alternative? They already killed Grooveshark. Now on to Spotify. Soundcloud is all that's left that's good IMO.
