search term playlists
This is a brief overview of how I manage a local music collection in $current_year. I use Music Player Daemon (MPD) and youtube-dl to index and add music to big “local music” folder. Over the years structure is totally scattered, but at least for the import folder (youtube-dl) things always look like this: ${musicdir}/import/<channel>/<title>. MPD has many clients, but now I use a script that operates atop the mpc client.
For quite sometime, my music playing looked like this:
mpc clear mpc listall | sort -R | head -n 1000 | mpc add
As you might imagine, this can lead to some jarring transitions and inconsistency with the ππππ.
MPD has a notion of saving and loading playlists, but you have to add files individually to them/it’s a very tedious experience if you want to incorporate many kinds of vibes.
Enter my version of playlist files.
Playlist files are files where every line is a comment, except for lines starting with + or -. At the moment, here is my jazz_piano playlist:
# artists +ryo fukui +hiromi +gabor szabo +kitajima +hitotaka izumi +Minoru Muraoka +alice coltrane # albums +flight to brazil # generic +piano +jazz +koto # channel +mogurin3131 +mogurin313131 +marcel the drunkard # edd ed eddy is actually pretty jazzy +ed, edd # random +touhou -05 My Sick Piano.m4a -Mario Basanov & Vidis - I'll Be Gone (ft. Jazzu) _ Chill_Deep-6zaOfkd84Z0.m4a -Dubmood - Bored at the piano-vQUlWsU_yZ4.m4a
Lines that start with a + are search terms against the current music collection (with a lenient grep against mpc listall) and lines that start with - are to remove search matches from the current mpc playlist. Removal is necessary because some search terms are so generic (here, piano). I then give music a function to process all the search matches. The advantage to this approach is whenever I add new stuff from an above artist or YouTube channel, it will automatically get added to the playlist!
The script may be found here. Here are it’s current options:
$ music music options: add : add a url to library, fallback on clipboard content append : append some search term to the current playlist artist : play songs by an artist bl : blacklist the currently playing song from the current playlist del : delete the currently playing song filter : filter the current playlist by some shell function acting on music files info : display the current audio progress bar and playlist length now : fuzzy search for a song, play it now playlist : select a search term based playlist to play remove : remove some search match from the playlist shuffle : reshuffle current selection from all
And an example of a fetch-like status (bar created with mkb):
$ music info Hiromi Uehara 2006 Love and Laughter ββββββββββββββββββββββββββββββββββββ playlist: jazz_piano | 60h 35m 13s

After some times passed with the above system, I found myself sometimes wanting more flexibility in playlist composition. Did you know you that - and + are valid function names in bash? Oh yes, we’re going to get dumb:
+ () { append "$@"; }
- () { remove "$@"; }
@ () { artist "$@"; }
. "/path/to/playlist"
Sourcing the playlist means the blend between music script and playlist is total, because playlists are now just shell scripts eval’d in the `music` context. What follows is my vaporwave playlist, where you can see I’m doing something silly and effective with ο½ο½ο½ο½ ο½ο½ο½ο½ο½:
#!/bin/sh # get any song with a widechar in its name for x in ａ ｂ ｃ ｄ ｅ ｆ ｇ ｈ ｉ ｊ ｋ ｌ ｍ ｎ ｏ ｐ ｑ ｒ ｓ ｔ ｕ ｖ ｑ ｘ ｙ ｚ Ａ Ｂ Ｃ Ｄ Ｅ Ｆ Ｇ Ｈ Ｉ Ｊ Ｋ Ｌ Ｍ Ｎ Ｏ Ｐ Ｑ Ｒ Ｓ Ｔ Ｕ Ｖ Ｑ Ｘ Ｙ Ｚ; do append $x done # artists @ HOME @ windows96 @ lucien hughes @ Macintosh Plus @ haircuts for men @ blank banshee # search terms + vaporwave + vapor + E m o t i o n a l T o k y o # youtube channel + elfamosodemon # give us stuff longer than 15min filter is_long - lazerhawk - saint pepsi - lofi - synthwave
This degree of control is fun because I can do things like “make a playlist of songs not listed in any other playlists” in addition to just being selective about broad searches.
Have fun with it! π¨
