I have terrible news. I had a couple playlists on my account. One of them even had over 50 followers. I checked my account just now to play some music at a party and ALL MY PLAYLISTS ARE GONE!! How is this possible? I searched for these songs for over 3 years and i can't function without my playlists. I hope you guys know how i can get them back!
You might have made a duplicate account by accident, which is easy to do with a Facebook/Spotify created account.
"Please get in touch with Spotify via the contact form. If you get an email back directing to the support forums, reply back to that email even if it is from noreply, and the support team will be able to take a look at your issue and you'll hear from them shortly. Spotify users can also contact Spotify customer support as well on Twitter with the @SpotifyCares handle, or on our Facebook page."
Customer support should be able to take a look, and see if there is more than one account with your Facebook details, and get things fixed for you.
