why is toxicity not on spotify

The album "Toxicity" by System of a Down was temporarily removed from Spotify, with many fans noticing the disappearance of most tracks except for a few like "Chop Suey!," "Toxicity," and "Aerials," which were listed under compilation albums instead. The reason for the removal was not officially confirmed but is likely due to licensing and rights issues, which commonly cause music to be removed if agreements between the band or their record label and the streaming platform end or change. Another possibility is adjustments related to digital distribution strategies or resolving internal disputes. The removal was brief, around half a day, and the full album has since returned to Spotify for most users. The band and their label, Sony, were reportedly aware of the situation and actively working on a resolution. The album remains available on other streaming platforms like Apple Music and YouTube Music throughout the incident.
