When you are in the My Library you will see the following icons to the left of your track information:
From left to right:
Favorite Icon : Favorites your track. This will also add it to your Favorites menu under the Tracks section
Edit Icon : Allows for the track to be edited. If this icon is grayed out then the track has been downloaded and can no longer be edited in Soundful
Share Icon : You can share any of your tracks through WhatsApp, Facebook, Twitter, Reddit, Email, or by getting a direct link to the track itself
GET/Download Icon : Before a track is downloaded this button will show as GET. This will start the rendering process. Once rendering is complete it will change to the download icon. This track will also then appear in your Downloads menu
