To do so, simply play the first track in the list and it should queue up all of the matching tracks in Spotify. If you want to save this as a playlist, simply open the play queue in Spotify, highlight all of the tracks in the queue, right click and choose 'Add to... new playlist".
Here are some of my favourites:
1. Last.fm playlists
Although technically deprecated, we kept these on the site so that people could export them to other services. With spotify integration, you can now play them again.
2. Loved and Banned tracks
You can now sort your loved tracks by play count and artist name, and then play them within Spotify. You can also play your banned tracks, if you like. :)
3. Top tracks and Charts
I think this is one of the most exciting features. You can now play your top tracks for any of the default time ranges (1 week, 1 / 3 / 6 / 12 months, all time), and of course save them as a playlist.
To get the spotify play buttons to load correctly, you might need to load the page in a new tab.
4. Weekly snapshots
Likewise, you can generate a playlist from any week of your charts, using our weekly snapshots feature.
5. Personal tags
Personal tag radio used to be subscription feature - now you can create a spotify playlist of any tracks you've tagged .

(artists and albums not currently supported yet).
6. Recent tracks and explore
Using recent tracks and explore, you can relive any scrobble.
