For producers, if someone purchases a lease or buys one of your beats, you have the option to white list accounts so they'll be able to earn income from their respective channel. You can just contact support in BeatStars and they'll do it for you.
This is another reason why I recommend people offer free downloads for at least a portion of their music. You don't have to give it all away for free if you don't want to, but the more people use your music, the more you get paid. It will take a lot of pushing and marketing to get popular songs, but it's worth it in the end when there's recurring income every month all from people listening without even buying.
To put some of the recent numbers I saw into perspective, one producer using Content ID made about $12K last month with about 37 million views across all his content. This guy has hundreds and hundreds of beats and has been building his fan base for years, but one thing will never change, artists and listeners love good production. There could be 1,000 videos using the same beat, and he's collecting revenue from all of them!
Keep growing in your knowledge of marketing and making better music and people will be sure to use your songs!
