Once you upload your music to Dishamusic, it will stay online indefinitely as long as your account remains in good standing. There's no set time limit imposed on the availability of your music across distribution platforms. If you choose to switch to the free tier, your account will stay active, and all previously uploaded releases will continue to be available in all stores. However, it's important to be aware that you'll be subject to membership limits, which could affect your ability to upload new releases.
