I have a huge collection of music videos that I am now trying to catalog. I play a lot of music videos in the background in my home (instead of just listening to music on the radio) so I like to create playlists with those videos.
I think it would be awesome if it were possible to make selections in Videonizer using filters like tags (based on genre or rhythm or other parameters) and actors (in my case: artists/groups) and then save that selection to an .m3u-file (for example) that I can open in VLC-player.
