After your release has appeared online, it will in principle remain "available forever" in the various stores. In theory a store can remove releases over time without giving a reason, but in practice this is rare. Furthermore, it can of course happen that a download store or streaming service is completely closed. If you want to have your release removed yourself, you can do so via the option “Takedown from all channels” (“Distribution” tab) with the relevant release, or email to info@mediafamous.com.
