Since I'm paying for the Premium version of Spotify, I get three (I think!) invites to give out a month. Now, I have forgotten all about the free invites until I checked them just now and I have 41 invites that can be gifted to anyone living in one of the following countries:

Sweden, Norway, Finland, the UK, France, Spain, The Netherlands or the US.

How it works:
All I need from you is a valid email which is not registered to a Spotify account already. Anybody who wants an invite, send me a private message with your email and I will send an invite. If you want an invite but do not want me to have your email, you can always create a new email account and get your invite.
