Updated: new method working 03-2015
I sell this tut on Hackforums for prolly 15$, made enough money so I share it here and everyone can profit from it.
This method doesn't include any carding methods, blackhat or cracking accounts. Everything is legal and you can probably make one premium account in just 30 secs.
You may want to start your own shop selling Spotify premium account with this. This tut is for reference only, i take no responsibility or anything relates to it.
Your Account will be upgraded to premium and you can do it unlimited times, no worries.
First, head off to https://www.spotify.com/us/ and register a new account. Then choose Upgrade.
