I understand MOG doesn't have a free version and that's the utopian dream of Spotify (so says Wired) --- but Spotify bled money out their noses last year. They were hundreds of millions of dollars in the red. I can't speak to MOG's profitability (I don't have info for them), but I guess as someone who lives in the States where people get sued over music, I look at Spotify and then at competing services like MOG and just sort of shrug my shoulders over $5/mo to get unlimited music onto all of my devices.
