that would be amazing. too bad it's hardcoded into the skin. if you change the default search in the browser to Wikipedia, at least clicking those will take you to something slightly more useful than AOL's search.. ML would be fantastic but would all depend on what Martin wants to do with it or if he's even able to due to some weird AOL promotion shit they force into Winamp.
One cool thing is that this functionality is available from the Playlist with ShaneH's MLFind plugin:

but yes, would be cool/intuitive to see it in the file info component too.
