Play MPE Encoder user can set up their release and enable Preview Streams. When this option is enabled, new users of Play MPE as well as those who may not have signed into their player in a while will be able to click on a preview link from Play MPE releases and stream preview-length tracks from any device. They will then have the option to open the song within the player and download or listen to full-length tracks. Those who already enjoy browsing releases in their player will continue to have that as their primary option.
To enable Preview Streams, please follow help article from here.
