In case your music directory is insanely disorganized, take a gander at MP3 Check. It’ll help you fix up all the gaps in your information, as well sort things for you.
Apparently, you can even search by things like gain and bitrate. That way you can find the quieter and lower quality tracks in your library. Not a bad deal, and worth checking out. You can download it here.
