I recommend VLC, simple, clean, supports playlists, sorts music by how you have it sorted, not by tags. Really all around good player for both audio and video.

It may prove to be a bit more basic than you'd like, but try Hero Kids.

Also FUDGE is free, very simple and word based, but it is recommended that you use special dice that are used with FUDGE/FATE.
