Do you miss Spotify's 3rd party apps? I sure do.
I'm trying to recreate the one's I used the most. So far I've been able to mimick KCRW's Music Mine.
You can listen here, or click the playlist title which will take you to Spotify, where you can 'Follow' the playlist. This will make it always available to you in all of your Spotify clients.
I'm trying to keep this up to date as best I can. It will always be a day behind, but if you find that something is off, tweet at me.
