Like practically all music streams N1M is run by robots. I was naive and stupid enough to submit my music over and over again... again: like with all these sites, you submit stuff, reach a ( virtual) goal and than: "get premium to get more exposure". Meanwhile the exposure that you received before premium request is generated by robots.
Luckily I didn't invest money, however I invested a great deal of time.
If you have the illusion that robots will give your music career a boost. THINK AGAIN
