Hi! You have several options:
- you can download your song as an mp3 or wave file and add it to your site (to download, go to the script browser (second icon from the top in the left bar), see the script you want to download, click on the blue menu icon on the right of the name of the script, and click on download).
- you can upload it to soundcloud (same process as above, except in the menu select share, and in the window, click on 'share on soundcloud)
hope this helps!
