hi guys,
This is just a quick "heads up" post. If you're not familiar with spotify, I recommend you try it out, if it's available where you are. It's probably the cleverest and slickest music app I've seen online since liquid audio (which became itunes music store).
Anyway..the heads up is that they've opened up to developers with a libspotify (C API package).
The following is from the spotify site:
Today we are delighted to announce the launch of libspotify, our first step in opening up Spotify as a music platform. By releasing libspotify we will allow third-party developers to write applications for our service and offer the possibility of creating an exciting new range of features. Libspotify and any applications built with it will be available to Spotify Premium users as of today.
With the release of libspotify we hope to empower our users to build upon what we’ve started and come up with imaginative and innovative new ways of interacting with Spotify. There are hundreds of features that users have suggested to add to Spotify and by taking this step we hope to encourage the developer community to expand our service.
Developers interested in using libspotify can head on over to our developer site for more details. Initially we are offering support for Linux on IA-32, but we have plans to open up Spotify to more platforms and provide additional access to our services in the near future.
Our developer site can be found at:

Invites for Drupalers
I've got some invites for anybody wanting to try out Spotify Free. No bribes required.
Awesome. Yes please.
However, I'm in the US... so that might mean no.
Another one of those site
Another one of those site with country limitations.
"Why is Spotify not available in my country?"
really annoying. also kind of ironic since their video starts "In a world where everyone loves music........."

Support for other platforms
I think waiting for all platforms to be supported would be a way to go.

Now that Spotify has landed in the US...
...I think there will be some renewed interest in integration. Looks like there's a D7 version of the Spotify module in the works! http://drupal.org/node/1067474
