you know how when you're scrolling through instagram and you get a message that an account you follow has started a live video? wouldn't it be cool if, when streaming music on PANDORA you could get a notice if one of the artists in your collection started listening / streaming music on Pandora, and you could join in as a part of the audience and listen to what your favorite artists were listening to!
something like this! a way to have a shared experience with artists you like / admire and to discover new music along the way!
