Is there any easy way to convert a Last.fm playlist, such as this one, to a Spotify playlist? (One which would include, of course, those of the songs that are available on Spotify.)
You can export playlists from Last.fm as XSPF, but Spotify doesn't seem to directly support XSPF imports.

Not exactly what you're looking for, but this website lets you create Spotify playlists based on loved tracks and recommendations. Maybe you can contact the guy who made it can adapt it if you contact him.
Edit: Actually you can use Playlistify to import XSPF playlists into Spotify.
