I helped a friend create an album track for a course about meditation. The track was registered and submitted via CDBaby to many streaming services whose now publish the track for free. My friend wanted to sell the track for $3 dollars, and that is the price on Itunes, but google sells it for $1 (like it or not as they dont allow price changes), and the track is not even easy to find on the google play music. I understand mobile platforms and the music industry made things hard, or impossible for us to use our devices the way we would like, and they are the big corps who will suck the money from everyone. I need a platform where i can sell that track, for $3 bucks, and be IOS and Android compatible. I took a look at soundcloud but i dont see the option to sell the track there. CDbaby sells the mp3, or i could sell the MP3 on the website yeah, but people are not familiar with a mobile file manager or how to have the track available on their phones after downloading. So i am looking for suggestions, where can i sell the track and be easy for the people to find it and play it once purchased on their mobile devices? Thank you
