Just noticed my music up for sale on a site by a company I have no agreement with. It seems that there are a number of companies setting up to offer streaming services in the near future that are 'data mining' material from other companies and then setting up that material for sale on their website and taking all the revenue for themselves. Because you have no agreement with them they are not obliged to pay you when someone downloads your material. So they do little or no work once their server/setup is in place and then take all the profits. It's a real dog-eat-dog world out there!
