Despite some noted differences in the discussion before why not team up with MonkeyRok? IMHO the arguments are compelling: Song Information Panel could be one of several (existing and future) panels within MR. Actually both use one or more possibly different looking panels to display extended information on the currently playing or selected song. That way the user could simply choose what to display within the common pane. Even though other panels in MR get information from Last.fm, the first panel of MR serves the same puspose as Song Information Panel, only in a much more limited way. Actually, I edited the code and html sheet of MR to habe some of the configurable information on the song from MM's database displayed nicer than in the predefined standard version: genre, publisher, original date and so on. It's information from the DB about the song being played displayed in a pane!
BTW: I even tested getting top tags and "# of plays" info from Last.fm and displaying it in MR (splitting top tags into genre, mood, occasion by whitelists). What I mean is: to me it's basically irrelevant if e.g. genre information about the current song comes from MM's DB or Last.fm. It's information about the song being played displayed in a pane...
