So, we all know that Spotify is flat-out awesome. Access to millions of songs....enjoying music we know, and discovering music we weren't aware of before. But one way to take it to a completely new level - in my opinion - would be to significantly upgrade/improve the social interaction between users. Spotify could easily become the Instagram of music. I am a bit older than most here I would imagine, and I keep up with friends and family through Facebook. But a big percentage of my posts there are music-related. The comments, interactions, discoveries there are really great! I am not suggesting Spotify change their core concept to a FB-like app, but sharing music needs to be discussed and I think Spotify could easily take the millions of users who are leaving Facebook these days.... there will likely be tens of millions of people leaving FB - Spotify could go get a good percentage of them! Develop the social aspect of Spotify, and the growth would be enormous. Just my opinion!
