Put all your mp3s in a single music folder and set the view settings to list files by name (or details). Name each MP3 file using a format such as "ARTIST - TITLE.mp3" (e.g. "Coldplay - Clocks.mp3"). To organize songs by album as well then do something like "ARTIST - ALBUM - TRACK - TITLE.mp3" (e.g. "Justin Timberlake - Justified - 05 - Cry Me a River.mp3"). Keep filenames readable/consistent and your songs will be listed alphabetically/chronologically by artist, album, track # and song title.
