In march 2nd I was listening to "crystal ball" by Keane, when suddenly the song stops and is replaced with "Change me" by Andy Cloud, which i've never heard of until that day.
I've tried to play "Crystal ball" several times, but everytime it was interrupted.
So I noticed that there were two PC connected at the same time, despite I've only one, and the other one was called "Web player (chrome)".
I've changed my password four times, disconnect all devices, and I also checked what apps were associated with my account, but nothing works. Whoever was using my Spotify, they've continued until they log out spontaneously.
However, today I've noticed a four days old e-mail from Spotify asking me to change my password, due to some suspicious activity. And after I proceed to do so, I've found twelve albums (of artists I don't know and who aren't among my favorites) in my recently played
I am thinking of creating a new account, but first I would like to know if there's a way to save this one, because the idea of losing 1500+ songs leaves a bitter taste in my mouth.

Hey @Serendipiti, thanks for reaching out to the Community!

I’m sorry to hear about this! In this case, I’d recommend checking out this support article for the next steps to take. On that page there is an option to get in touch with Customer Support if you need more help. 

To prevent this from happening in the future, there are many measures you can take to protect your account, such as resetting your password every few months, and not using passwords you have used on other sites. There is also a great guide here for some more measures on protecting your account.

If you see an email from Spotify, and can’t tell if it’s legit, use this checklist. Of course, Spotify makes sure that all user records and platforms are completely secure around the clock.

If you would like to start with a new account, you can check out this guide which includes info on how to transfer music from one account to another. 

I hope this helps.
