Help › Blocking MP3 downloads
You can use the Box.net widget to restrict users from downloading MP3's while still allowing them to stream or play the files. Once the widget has been embedded, click on 'MENU' shown on the top-right side of the widget and select the 'Settings' option. On the pop-up window select 'no' next to the option that reads 'allow mp3 downloads for visitors' and then click on 'OK.'
