Last.fm HD radio stations coming to major US cities
To tune in to the actual stations you'll need to be in LA, New York, Chicago or San Francisco, and have an HD radio. That means this might be a bigger win for HD radio adoption in general than for Last.fm in particular. If people are going to start buying HD receivers, it'll be because there's enough quality content to make the investment worth it. Last.fm's stations might be a good start.
If you're not, though, you can still catch the online streaming version of the station through the Last.fm site or through Last.fm's mobile apps. Listeners can also expect in-studio performance and interviews from a studio Last.fm has set up in New York. With data from over 25 million users, Last.fm might be taking the mystery out of the formula for radio success. I wonder if they'll dig up some obscure gems, too, or whether it'll just be the popular stuff.
