I am a MP3 fan and I usually gather them in different folders by certain criterions, such as singer, genre, style, language, author etc. But I have to create a playlist for playing all files that I am interested. However it is different since I get a handy and powerful MP3 player that can play all MP3s in a directory. That is 1by1 which was published by Martin Pesch.
