I have been playing with the Last.fm Radio Player Widget. It allows you to make a playlist from songs available at Last.fm, which you can then share via your own website, MySpace, LiveJournal, or whatever. In theory it is very cool, but I don't think it works correctly. It seems to pick 5 or 6 tracks and stick with them regardless of how many are in my playlist. I have tried this with playlists containing 15 tracks all the way up to nearly 200 tracks and got the same results. Hopefully they'll fix it soon. It will be fantastic when it works properly. In the meantime, it still sort of works OK.
Launch Last.fm Player Script
Here's a little jQuery script to launch the Last.fm radio player widget in a new window. It depends on the jQuery Javascript library.
