Songler (formerly SpotifyMCE) is a fantastic add-in for Windows Media Center for playing music content from multiple legal streaming music providers - currently Spotify, Last.fm and YouTube. It is the first Add-In for Windows Media Center to play Spotify content, and the most up to date Last.fm Add-In. It allows both free and premium Spotify subscribers you to play any of Spotify's 6 million tracks instantly, directly from your Media Center, all controlled with your remote. It also allows you to scrobble the tracks that you are playing in Songler to last.fm to build up your music profile, and last.fm subscribers can stream all of their radio stations too.
