Allow listeners to download songs from shared Songer links

Description: Right now, when a Songer song is shared via link (e.g. on Facebook or messaging apps), listeners can stream the track and view the lyrics, but they cannot download the audio file. Many users are currently working around this by manually downloading the file and sending it via email or other platforms. It would be very helpful to add an option that allows the creator to enable or disable downloads for shared links. This would make sharing music much more flexible and improve the overall user experience for artists who want to distribute their songs quickly. Use case: Share song on social media Allow collaborators or friends to download directly Reduce need for external file sharing tools Impact: This would streamline sharing and make Songer more useful for creators who distribute their music outside the platform.
