Basically what the title says. DJ authenticates their SC account within Serato. Through the side menu, able to stream load their favorite or searched tracks to the decks.

Obviously risky when playing in a public setting, but as a feature in of itself will be VERY beneficial. Especially with exclusive tracks.

Mobile DJ apps such as Cross DJ on Android does this beautifully. As a professional, I would love to have this with my Serato suite.
