I haven't upgraded to OS X 10.3 yet, so I can't try this, but the way Macintouch describes it, "Mobster" sounds cool.
Mobster 1.1 watches the music you play in iTunes and uses recommendation information from Musicmobs to suggest other music that you may like. It includes iTunes control, playlist creation, library browsing, and an option to weight recommendations with a slider that ranges from Mainstream to Hipster.Posted by jackhodgson at December 31, 2004 11:26 AM
