Freeware utility for Itunes

Tag your iTunes music by mood with the freeware, color-based tagging utility Moody. While your music is playing, just pick a color for the song with Moody's 16-color scale (sad to happy, calm to intense).I have set a red colour for my Thug's Party playlist(A playlist of all my uptempo songs) :D

Once tagged, Moody writes the mood to the comments of your song's metadata (it'll look something like MoodyC3). You can either use that metadata to create mood-based smart playlists or just use Moody to fire up a playlist based on your mood. It may sound a bit tedious, but if you put Moody in quick tag mode, you can tag a lot of music pretty quickly. Moody is freeware, Windows (with .NET framework) and Mac OS X only.
