I would be fine with getting paid just the odd dollar if not for the fact that someone else is making actual money by using my music. If I had the money to enforce certain clauses in certain contracts I would make sure I didn't have to worry about it.
Ah, so to be clear then, you're talking about your record label(s) making your music available on Spotify, and you don't really have an issue with Spotify itself?
When I do my calculations, I always use the payout figure that Spotify pays to the rights-holder of the music, whether that's a label or an independent artist. How the label decides to share that payout with an artist is opaque to me, is different in every case, and really has nothing to do with the is-Spotify-bad-for-music issue. That's just the age-old label-vs.-artist issue, which exists in similar form regardless of the medium.
For the record, Spotify has lost money every year of their existence, and over 70% of their revenue has gone straight to licensing fees to labels/artists, so *they* certainly aren't making money off your music (yet).
Finally, while music as a whole is quite valuable to society, simple economic laws involving supply and demand, combined with the 76,785 albums released in the US in 2011 (equivalent to 211 new albums every day), reveal that any single artist's work *is* of almost no value. In my mind, the smart and talented guys are the ones who have been able to convince us of the
opposite and get us to pay as much as we have for the last 30 years.
