On a general note about this plugin, when I wrote it, I had only recently switched to MB from Winamp. I used to right click > play folders with Winamp, and initially did that with MB too, which is why this plugin was helpful. But now I have discovered the power of auto playlists, and they can be setup to filter by tags, so now I have a shuffle a playlist with rule "SKIP_OVER_SONG is empty", and I get basically the same effect.
The skip section of song part of this plugin could still be useful, but skipping the end of a song is often more important for me (like when the last track on an album has a 3min song, then 10min silence, then a 3min bonus song). At the time I wrote this plugin, a MB couldn't do that, and I haven't looked to see if MB API has enable that since.
