Everyone who signed up on April 2nd or April 3rd (as announced here), to test Your music features, has now been given access. Your Music should be enabled for your Spotify account and you have access o our beta forum.
You should see Your Music show up on your different devices and desktop, sometimes after logging out and back in again.
Some folks still have some trouble entering the right info in the form, and may have been missed. If you signed up and don't see the Beta teser forum in the community (make sure you're logged in, in the community, first!) please reply here and I'll see what I can do for you.
If you were too late to sign up, there's no need to reply here. The best thing to do is make sure you go to the beta testing post and subscribe to it. That way you will be informed when we post an update.
