Songwriter Andrew Fromm is making some good money on Tsu. Certainly more than he gets from some streaming sites. He has nearly 24000 followers there, but he also has a large network of people he signed up who make him extra money. One of these is Kimberly Henderson who has a viral hit song on Youtube. She's doing well from Tsu too.
It seems like a good site for artists to make some extra income from their work. Still relatively small as social networks go, but if they can get more cool artists on there it should grow.
You can join with my link https://www.tsu.co/steevc. Yes, I stand to gain, but I don't see me getting rich from it. Just want some extra pennies for the guitar fund :)
