Add a messaging system to the Spotify mobile and desktop apps to easily share and talk about music with your friends!

I've been wanting a messaging system on Spotify for a while, inspired by this crazy, yet true story: Over a year ago, somebody my friend followed on Tumblr didn't know if their fiancé had died, since they thought he was in a coma. They then found out he wasn't dead, for he was listening to music as seen on Spotify friend activity. Their relationship was estranged and Spotify was the only way they would've been able to contact him at that moment, but it wasn't possible, due to Spotify not having a messaging system.

Aside from the story that inspired me, it would simply be a terrific addition to the platform. Thank you!
