MPDQ ======== Automatic MPD playlist creator to provide a bit of complexity and randomness while autoqueuing MPD, but without relying on external services like Written in BASH so that if it doesn't quite meet your needs and to make it a bit easier to prevent having bitrot. ## Requires * [mpc]( * [ffmpeg]( * [zenity]( ## Setup ### Tag Music Files * Make sure your music is properly tagged with the genre and that the BPM values are set. You might find my [bpmhelper]( script of use with the latter. ### Configuration Files * Create $HOME/.config/mpdq * Place mpdq.rc in $HOME/.config/mpdq This file (example provided) contains only the following lines in *this specific order*: ``` /directory/to/music hostname.of.mpd 6600 password number of songs to maintain in queue range for bpm time (in hours) to avoid repeating song ``` The bpm range is *not* a percentage; rather it's a set number. So for example, if the currently playing song has a bpm of 130, a value of "10" there will provide matches of songs with a bpm range from 120 to 140. ### Setup Commands There are three setup switches: -s, -g, and -f. * -f: This switch runs both -s and -g * -g: Genre matching. The program will present you with lists of your genres, using Zenity, and you can pick which genres "go" with other genres. For example, you might determine that "Acoustic" goes with "Singer/Songwriter" and "Folk" and "Celtic". If a genre has already been matched, you are *not* presented it again. This information is stored in plaintext in $HOME/.config/mpdq/genredefs.rc . * -s: Song scanning. Because MPD does not store BPM values in its database, this switch tells the program to scan every song file in your main MPD directory (using the ffprobe function from ffmpeg) and writes the information we need to $HOME/.config/mpdq/songdefs.rc . It will not rescan files it has information for, so while the first scan will take a **LONG** time, further scans should go more quickly. ## Usage Run `mpdq` without any arguments. It will loop with MPD's event update cycle. ### Switches * -b switch to just have `mpdq` match via BPM, not genre. * -j Matches are to the *currently* playing song. This can provide more diversity, but also means that the genre can jump or drift. For example, if *Pop* matches to *Dance* which matches to *Electronic* which matches to *Darkwave* which matches to *Industrial*... you're waaaaay away from Cyndi Lauper awfully fast. * -k Kills a running `mpdq` process. The idea is that you can run `mpdq` in the background and then invoke it again to kill it. ### Startup Things The Program Does * On startup, it deletes old entries in the logfile of songs that it has played (located at $HOME/.config/mpdq/playedsongs.log). It does this task approximately every hour of continuous operation. * This program turns on consume mode and starts MPD when it begins. * If there is an empty playlist on program start, it randomly picks a song and starts playing it. * Best practice is to start playing a song in MPD before starting this program. ### Operation The program first looks at the *initial* playing song. If there are matching genres already configured, it picks one of those genres randomly. From that set, it narrows it to songs within the defined BPM range. And then it checks to make sure it's not been played within the user defined length of time. If the first match doesn't work, it tries again with a slightly wider range of BPM values. It repeats this up to ten times, and if it still cannot find a match, it will try to find a song within the original BPM range in *any* genre. Rinse and repeat. # TODO * Progress indicator for song scanning * Way to (easily) indicate that some genres are "better" matches than others * Ways to blacklist some songs or genres Playlistmaker ======== This is created so that you can create static playlists based on "smart" criteria like combinations of *genre* and *bpm*. (See `` for a way to create a playlist of songs recently added to your system.) This utility *only* works in combination with the `mpdq` database, so you have to run `mpdq -s` at the very least so that it can scan your music files. It's pretty self-explanatory - it creates playlists with a default of the current date and time in $HOME/.mpd/playlists, though you can choose the location. Then you can select as many genres as you want, the BPM you want as the centerpoint, and the range you want (in percentage). It'll spit out a playlist you can then easily play in MPD.
