It seems to me as if most streaming services provide basically the same content and functionality. May I suggest a feature called Spotify Stories, where the licensed music content is interlaced with files of spoken audio that provide some information and background to the music? This content could of course be anything, an obvious candidate is an artist choosing their favourite tracks over their career and telling the story behind them, but you could also, say, track the history and development of everything from the classical symphony to Detroit techno. It would be a great way for people to learn more about their favourite music and for an artist to connect with the listeners. And as these additional spoken files would be proprietary it would give people a reason to choose Spotify which is based on actual content rather than price and/or (for most listeners perhaps less than essential) social networking features. (This goes for playlists as well. I don't know how popular those Barack Obama playlists were for example, but surely it would have been considerably more special if he had just said a few words about why he chose those particular tracks.)
Your Idea has been submitted a while ago, and unfortunately hasn't gathered enough votes (50 votes within 3 months) to keep it active in the Exchange. Be sure to know that this does not mean that your Idea has been declined by Spotify.
Don't worry, your Idea will still be able to gain more votes, and may get a Live Idea status if it receives enough of them.
