Differences (that I don't understand) between Spotify and Pandora Music

My original piano music is available on all digital streaming stores. The thing that I don't understand is the fact that between the listeners who listen to my piano music on Spotify and Pandora Music there is a huge numerical difference. During the whole year, I have on Pandora at least more than 1K monthly listeners (today, June 13, 2025, I have about 1.7K listeners on Pandora).

While on Spotify, excluding Christmas time, I have about... 150 monthly listeners. So, the listeners of my original piano music on Pandora are 10 TIMES more than on Spotify!

In addition, it must be considered that the Pandora service is accessible only in the United States, while Spotify is accessible... worldwide!

Considering that my original piano music is on the exact same way on both stores, I thank and am so grateful to the Pandora Music Team for have added my piano music to their editorial playlists, REALLY helping my piano music grow.

While it is clear that the Spotify team does NOT do the same!!
