"When something vanishes, most of the time it is because no one cares about it anymore" Plenty of music that I listen to is not available at all on Spotify. Some of entries will never be there (for example, I have some private recordings of music done with my family). Some cases are not economically viable to be published, but it is not the same as "no one cares about it".
