Spotify uses Klout Perks as part of social influencer strategy

Spotify's much trailed launch in the US this week is being supported by a great promotional partnership with Klout, the social media scoring site.  Klout has been using its "Perks" as a means of monetising its highly socially-engaged user base.  

Nice to see a clear "Influencer Code of Ethics" too:

• Klout will never sell or give away your contact info.
• Participating (or not participating) will not change your Klout Score.
• You are receiving the perk because you are influential and have authority on topics related to the perk. You are welcome to tell the world you love the perk, you dislike the perk or say nothing at all.
• If you decide to talk about the perk, we will ask you to disclose that you received a sample (klout.com/perks/disclosure).

It's a good win-win.  The Klout user base gets special access to products, movies or services and brands that pay for this get access to a potentially influential group of consumers.
