Basically, what the topic says.
I used to use foobar 2000, and that has a plugin for last.fm (
http://www.last.fm) but since using the Jukebox I've not been able to update my profile.
I'm thinking of writing a small app to do it, but it needs to know what songs have been played. If SK Jukebox could write the songs/artists to a test file as it plays them, that would be great.
Possible?
