My group still meets and plays in person, but last weekend, we were doing a D&D Next playtest. Due to a printer malfunction I had been unable to print out my character sheet, so I had my netbook open to read the PDF file. On a whim, I loaded up Roll20 in Chrome and started playing some background music in the jukebox. Everyone thought it was pretty cool, as I was just typing in keywords, like "battle music", and playing whatever came up. It definitely added something to the session.
