I've always sorted my music my own way on my computer. I have a structure for albums and one for singles, then sorted by genre. The system works for me and I've been using it for over 10 years. That said, it doesn't seem like the Droid's stock media player will cooperate in that sense. I can sort by folder, but it's meaningless as the Droid doesn't look at them. Is there a media player that will play based on folder? I'd rather not create playlists.
