MANY MUSIC CREATORS want to be exposed on the INTERNET! They join websites to present their music to the public and to get publicity.
What they don't know is that many of this websites, webcasters and companies are not run by people in the music business at all. They have just set up a website, as cheaply as possible and have no clue as to how to market music of any kind.
One such website claims to be run by a corporation which doesn't exist; it's really being run by a man who earns his money selling mundane products for home and business. He has no qualifications to be in the music business but had a few websites and domain names sitting around useless so thought he'd start exploting musical artists.
The user agreement on this website is a joke. Was it written by anone who knows anything about user agreements, the law or music? No, it was written by people who have a vacant space between their ears who stole bits and pieces from other use agreements.
The key question: does anyone listen to the music on the website. Maybe a handful of people who have no ability to do anything for any of the artists on the website. The website is just users listening to other users' music and none of those people know how to promote anything into a major career.
So, be careful when uploading your music to a website for exposure, you're not getting any where it matters.
