i have alphabetic playlists: a-e, f-j...etc
then within those play lists i have each individual letter a,b ..etc
then within each letter i have the artist, using the first letter of the group name or artist name...this way i can fine the artist pretty fast

then within each artist i have a playlist for each album...or a separate playlist for individual songs.

also..i have playlists for genres as well

took a bit of time but very organized and easy to find what i want
