Playlister is a little program to create and execute easily playlist, for MP3, Movies, and more.
It is intended for people who want to play their music, easily, but without any of the bulky gui’s that Music players come with now-a-days.
Instead it sits quietly inside your system-tray. To play some music, just right click on it, select your music, and click.

Also it is compatible with you favourite music player. As it does not do the playing itself, it calls an external player.
This does not mean you need some external player before you can start playing. You can just use the build in windows media player.
