I’ve written a simple plugin – which I’ve imaginatively named “Last.fm for Sweetcron” – for use with the Sweetcron lifecasting software. You add your loved tracks/recent tracks feed, and it uses the Last.fm api to grab a load of extra data as the feed items are being added to the database – album/artist art, track info, wiki entry, artist bio, etc.
For more info, check out the Last.fm for Sweetcron project page.
I’ve also written an Xbox “recently played games” plugin which I have running on my own Sweetcron install, which still needs some tweaking. Damn Microsoft and their lack of API is making it difficult to get accurate data, but once I’ve worked my way round the last of the problems I’ll release what I have.
