Last.fm will now stream Spotify's catalogue of 20 million songs

Last.fm and Spotify are now on the same team. Sort of.

From today, Spotify will allow Last.fm’s 55 million registered users to access its catalogue of 20 million songs, meaning they'll be able to browse individual tracks, full albums, playlists and recommendations and listen to music on demand. This capability is supported in all Spotify markets.

Spotify is a popular yet still relatively small streaming service, so is probably exploring ways to get more users and widen its marketing footprint. A partnership with Last.fm is just the thing it would need to accomplish both tasks.

From now on, whenever Last.fm users play a song, Spotify will appear in the background, with playback controls at the bottom. All grouped tracks on a Last.fm page will also show up as a Spotify playlist. This type of simple integration means maximum reach potential for Spotify.

Last.fm users will need to sign up for a Spotify membership or sync their Last.fm profile with their existing free or premium Spotify account in order to start listening on-demand. That said, the Spotify-Last.fm integration currently doesn't work in mobile browsers.
