Last.fm, the music streaming service that uses social tagging to find custom-tailored tunes, will be requiring that users of the iOS/Android/etc. apps pay $3/month for a premium subscription. I have found it convenient to listen to Last.fm on my iPod on more than one occasion, so this is a little disappointing.
Microsoft says that they plan to subsidize Last.fm for Windows Phone 7 and Xbox so their users will not have to pay the subscription.
This change will go into effect on February 15.
