Spotify may not have the massive marketing muscle behind it like that of new entrant Beats Music, but the small streaming service is looking to expand its reach in other ways. Today, the company announced a partnership thatll see the entirety of its music catalog made available for playback on Last.fm. Now, when Last.fm users click play on a track, Spotify will be launched in the background, with a convenient bar for playback controls appearing at the bottom of the screen.
