Someone subscribes Spotify with my email address

[Johnny_]

Hi,
I have a problem.
I have never used Spotify in my life, but i have received an email from "Spotify (no-reply@spotify.com)" this morning.

The text of email: 
Welcom to Spotify Premium

Hello (username),
Thanks for taking our 7 days free trial! If you'd like more time to discover Spotify Premium, click the button to enjot another 30 days on your device for free.

At the bottom of that email there's my email address
I have reset the password, so the account is really mine now (i hope)

Should i worry about that?

How to delete that account?  

Thanks
