Justice, I still haven't been able to make it recommend a single song.
It crashes. (using 5.51 here).
Same for the musicIP plugin. It has a mind of its own. I have all my collection analyzed already, I'm sure the MIP tags are on the files, not in the db. Still, the plugin window shows 34000 tracks, 34 left to validate, and pressing the button does nothing.
I have no idea when it's analyzing, or doing what... but it sure doesn't work.
Will post at the MIP forums.
PS: the winamp process is reading from the HD, so it might be doing something. No progress bar or numbers, like the gracenote one does.
