What can be the next 5 features for Spotify?
Playlists can be the place for user interactions. So the listeners can comment, like, share these playlists more easily. Spotify can boost the most popular ones at the landing page.
Playlist images can be customised, so users truely own this playlists. (Rdio does this.)
Stats must be real time. So the users can see who and what they listened to yesterday, last week, last year etc. easily.
Artists can create profiles, groups, pages etc. to meet with their fan base and make announcements.
There can be an option like that, Play ethnic songs from Malaysia. Country and genre can be changeable. (This is a personal request)
