NB: I really don't think anyone should be using this as-is, but if it helps inspire someone, great.
If you put together something better than what I have, please let me know.

There is a python fork of this project at https://github.com/bonelifer/mpdignore. I'm probably going to continue to use these so they'll continue to be "developed" such as they are...

This is a repository of mpd-related scripts that started as system service to ignore reviled or otherwise unwated songs (e.g., the 53 live/bootleg copies of Grateful Dead -- * - *Space*flac in my collection) by creating a .mpdignore file in the song's directory (e.g., /library/music/artist/album (YYYY) if so organized) so that mpd won't ever force you to listen to it again. (MPD removes it from it's library but leaves the file alone so if you want to listen to a complete Grateful Dead bootleg with "Space" wtih VLC because you're so fucking baked it seems like a good idea, you ostensibly could.)

Most of the core mpdignore scripts use GNU shit that should be packaged with linux. The playlist, played, etc., scripts that interact with mpd require gum. If there are other things necessary, they'll eventually show up here.

When the user choses to ignore the current mpd recording (mpd may be playing or paused) by $ ignore the the song path is recorded to a playlist: mpc current -f %file% >> "$pldir"/.mpdignore.m3u . mpdignore is designed so that mpdignore.path monitors the first playlist, i.e., /path/to/mpd/playlists/.mpdignore.m3u by default. When song paths are added to this playlist (e.g., by calling $ ignore while mpd is playing a reviled song), mpdignore.service scrapes this file, does the ignoring, and empties the playlist (as such, .mpdignore.m3u should normally be empty if the mpdignore working properly). You have the option to skip the currently-playing song.

Logging example, line 1 comes from mpd, line 2 comes from skip.sh in this repo:

Mar 25 11:46 : player: played "B.B. King/B.B. King -- King of the Blues (1992) (mp3)/B.B. King -- 03-08 - Niji Baby.mp3"
Mar 25 11:48 : player: skipped "Van Morrison/Van Morrison, Lonnie Donegan & Chris Barber -- The Skiffle Sessions: Live in Belfast (2000)/Van Morrison, Lonnie Donegan & Chris Barber -- 03 - Goin' Home.flac"

The second playlist, /path/to/mpd/playlists/mpdgnored.m3u keeps a running list of all such reviled songs that have been ignored so that one could e.g., use the playlist to torture your favorite Panamanian dictator ousted by your favorite American imperialist president—or you could just go back and check to see what files you've ignored in the event you wish to e.g., verify what's been added. (It's a feature I've NEVER used despite thinking I might.)

The rest of the shit in this repo is just stuff I don't really have a better place for and they're all mpd related. Someday I'll probably never get around to organizing it better since I'm outta fucks to give...
