I just woke up this morning and saw that I can't login intro my Spotify account.
I said to myself "Maybe it was deleted or something".
So, I reached to the support and found out that the email was reverted back to my old one, before I started to use aliases for my accounts. The support guy sends me a link to reset my password, because that was the only thing I can do, and got access back to my account.
Also, I realized that this was a great Halloween scare!
By the way, the support guy was named Marvin, great guy!
