How do you ensure the price of a song stays consistent day to day?

The listener does not pay directly for each play, the artists are paid from a rewards pool and the size of that rewards pool is determined by how many subscription fees are being paid, and how many EMT are remaining to be claimed by artists.

The price paid to artists per second will vary frequently, based on the number of visits to Emanate and the total seconds of audio streamed within a day. 

Although this varies, the platform has complex algorithms that will ensure artists earn a consistent amount per day based on the % of their plays on the platform and overall popularity.

Like any other craft, the artists who build an maintain the largest engaged group of followers will likely receive the most earnings via their plays.
