Beginning February 15, Last.fm will require a subscription to stream music to your iPhone and it will be ad-free. Here's what Last.fm's VP of production, blog Matthew Hawn had to say:

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.

Interestingly, streaming to mobile apps and on home entertainment devices will become an ad-free, subscriber-only feature with the exception of Windows Phone 7 and Xbox users. The ad-supported model will also still be available on the desktop app.

A Last.fm subscription is reasonably priced at $3 per month. You can sign up here.

For the cost of a fancy coffee, a Last.fm monthly subscription allows you to listen to radio across all platforms, on all your devices, and without commercial interruptions.

Any Last.fm listeners planning to subscribe?
