I don’t know when this hit winamp’s featurelist, but it is a beautiful beautiful wonderful feature. yes, i wish it did its magic by somehow analyzing each individual trac and gleanning the beat, mood, style, feeling to interpolate that into automatic educated playlists, so that it wouldn’t need to know the music in order to match them. however, its library of knowledge is really quite impressive, and its matching ability is even more impressive. it’s my new very good friend. i still listen to my music by loading all the thousands and then hitting “shuffle” and “repeat”, but then once a song hits that fits my mood, i run musicmatch on it, enqueue those, and let it continue on shuffle as it cycles through those mood-fitting songs before continuing on its random path.
i haven’t tried the standalone program… just discovered it as a feature in winamp a month or so ago. *happy*
