I was looking for a way to display my last played Spotify track on my website. I succeeded using the Last.FM API. Spotify doesn't have an open API and the music part of Facebook seems to be locked down too. So I now scrobble everything to last.fm and use their API to get the last played song. This works fine, but I thought it would be fun to display a "play now" button to play the track on spotify.
To do that, I need the Spotify ID for the particular song, which the last.fm api doesn't seem to return.
So... two questions: 1) is there a way to get the same info from Spotify itself? 2) if not, is there a good way to get the matching spotify song using the Last.FM details?
