The company sites on its blog the music industrys rapid change for the decision, which could be referring to the overwhelming popularity of services like Pandora, Spotify, and Rdio. Last.fms radio streaming service never matched the popularity of its competitors, even if it did have a following in countries like Canada and Germany. Piggybacking on Spotify and other services like it could get Last.fm tracks in front of more users and make a bigger impact that the radio streaming service did overall.
