If you love listening to Last.fm on the go, or via a connected audio device in your home, then we're afraid that we've got some bad news - the music streaming service has decided to go pay only for its non-desktop offerings.

Apart from the Last.fm website, which stays as it is, only the Xbox 360 and Windows Phone 7 devices will still have access to free streaming.

That means your iPhone, Android device, Logitech Squeezebox, Sonos system, Revo AXiS, Ikon, Domino or Heritage device, Roberts Stream 63i, 205, Colourstream and 83i radios, Teufel machine, Onkyo AV receiver and Denon and Marantz AV receivers will now require a Last.fm subscription to work (some devices will still have free access until summer 2011).

Speaking via the Last.fm blog Matthew Hawn, Last.fm's VP of products said:

"On the Last.fm website an ad-supported, free-to-listeners model is what supports our online radio services in the US, UK and Germany. In other markets and on emerging mobile and home entertainment devices, it is not practical for us to deliver an ad supported radio experience, but instead, we will migrate to what we believe is the highest quality, lowest cost ad-free music service in the world.

"We believe our radio - whether it’s a personalised station or artist and tag radio - is the best in the world and we’re proud of the depth and range of our catalogue of music from major labels, indies and unsigned artists. We’re committed to building Last.fm into a bigger service that gives listeners the best music discovery experience anywhere while financially supporting and promoting the artists who make the music we love."

The move puts Last.fm more in-line with Spotify, who require users to have a premium deal in order to get the service on their phones or connected devices.

The revamp only affects the radio aspect of Last.fm’s services; scrobbling, music and event recommendations, social networking and community forums, and Last.fm’s wiki-based artist information remain as they were.

The fee is £3 per month and you can pay up front for up to 12 months, or set up a recurring monthly charge. All the details can be found on the dedicated Last.fm subscription page.
