Not exactly karaoke more filler music oriented

[DanG2006]

I had been using Winamp for my filler player.
I want something better.
Have to be able to set to automatically stop after the song that I want to play last before going back to karaoke. Also has to play video files. Specifically mp4. So far I have only found Winamp. Must work alongside Compuhost.
Must be able to add songs to existing playlist on the fly or automatically add songs to the database downloaded into target folders while playing.

Found out Mixx DJ will do what I want. Great backup to VirtualDJ which I have decided to go with.
