Not exactly, but they have similarities.
Pages read on Kindle Unlimited (KU) is how Amazon compensates authors based on how many pages of their book are read by KU subscribers. Authors earn a portion of a monthly fund depending on total pages read.
Streams on Spotify count how many times a song is played for at least 30 seconds. Artists earn royalties based on a fraction of a cent per stream, depending on factors like the listener’s country and whether they use a free or premium account.
Both models pay creators based on user engagement rather than outright sales, but KU pages read is more like a pay-per-use model for books, whereas Spotify streams function as pay-per-play for songs. The key difference is that KU earnings come from a shared fund, while Spotify pays based on a revenue-per-stream system.
