Song value is based on expected streams looking at previous data, such as streaming history and social following. The artist makes this estimate when creating a campaign, but the streams needed to reach the goal is shown on the campaign presentation for you to evaluate. Corite also shares other data such as social following and a comparison to other songs out there. Naturally a low goal is easier to reach and a large social following can translate into more listening. But remember, we can never guarantee how many streams a song will get. Investing in a work of art always comes with a risk and you are responsible for making the decision.
