Thought socially outdated idealization of the musician/groupie dynamic had disappeared? Think again! The new Spotify/Doritos/Guitar Hero promotion positively revels in it.

Your aim is to win an all-expenses paid night in a hotel room, where you too can play Guitar Hero and eat Doritos just like a real musician! Or like you usually do on a Saturday night, just in a nicer room.

The way you do this? By signing up to their website, connecting it to your facebook and getting as many groupies as possible. And those groupies? People you know on facebook. Obviously the Spotify/Doritos/Guitar Hero triumvirate wouldn't want to be involved in any potentially illegal coercing, so it's all a matter of uploading nice benign pictures of people's underwear - unmodelled. But wait - do I see all male images of musicians and pretty frilly pink girly underwear as the groupie icon? yes I do. Sure, you can win by accumulating fans too - but when groupies gain you four points and fans a mere one, it's pretty clear how this is going to be won.

I've written to both Spotify and Doritos asking them why they've chosen to incorporate such sexist ideals into their promotion. I await their reply.
