Here's how mine are organized:
mp3 CDs are organized by genre, follow by number: ie jpopMP3_20
Inside the CD are directories of artists, with subdir of album name, follow by bitrate. ie Hamasaki Ayumi\Surreal (320_2ch)
after I burn a CD, I do a tree, and a dir/w/s of the CD's root, > into a file.
I burn 2 copies each time, one for use, one for offsite backup.
and then I have an excel file with different worksheets for different genre, all the albums listed in A-Z order, the bit rate, the CD name it is located in, and a hyperlink into the text file with the CD's content.
