If you can't find Diving for Pearls' self-titled debut album from 1989 on Spotify it's possible this release isn't currently available in your region. The availability of content on the platform can vary over time and between countries, depending on agreements between Spotify and rights holders, such as artists or record labels.
However, we add new content to Spotify every day, so if you can’t find the album right now, it may still appear in the future. Alternatively, you can contact the artist or record label with your query or make use of the local files feature.
Hope this helps. Let us know if you have any questions.
