Realized what an idiot I was for not using MPD's database,
so removed external tool tagging/tag reading requirements. Makes things
a LOT smoother, especially since ffmpeg and exiftool was where most people had issues.

Added "radio station no repeat" (don't play the same song AGAIN for X
time), fixed bug with weight matching, fixed error if there were
multiple copies of the same instruction.

Of course I forgot the docs

Added weighting properly back in

* Fixed bug where tracks > 60m would pass through length filter
* Redundancy add - if "artist" tag is empty, "album artist" tag will be used instead for artist frequency. Likewise, if "album" tag is empty, the "title" tag will be used instead.

Because of course you notice it after you tag it.

Significant rewrite, making it a single-run process instead of loop

Incorporated some fixes.
Cleaned up code getting tag info when needed.
Explicitly added requirements for helper programs.
bugfixes
Note change in config/cache paths!

Formally added prerequisites for getting MP3 information
Fixed a time bug
Fixed a bug on pausing

Added way to keep song repeats separate from genre repeats

mpc search returns if there's a *SUBSTRING* match
mpc find will only return exact genre matches

Bugfix for genres with spaces

Whole mess of bugfixes with rotation and matching
Introduced way to limit length of selected songs
Introduced way to not have the same artist within X period of time.

Fixed error with logrotation, genre rotation option

Pre-release to test genre weighting
