I tend to make most of my playlists with Spotify, but I don't solely use Spotify to listen to music! I would really like to see a feature for exporting a playlist to a file, .m3u, .pls, .txt what have you, as long as there are hard links to my local files in some type of container I'd be ecstatic. It'd save me so much time rebuilding playlists and would serve as good backup too!
