This script is an updated version of my script to display playing music title on website. It will write all the artists, tracks and albums to a MySQL database.

Update 2021-12-29: Amazon redesigned the output via alexa.amazon.de, the string for “album” is now always empty, so can only get the state, artist and title at the moment. If you use Spotify you might want to check out my Spotify script. I also thought about a way to get an album via artist and track out of a musicdatabase (like musicbrainz) but I dont know yet if this will work.

CREATE TABLE `album` (
  `artist_id` smallint(5) NOT NULL DEFAULT '0',
  `album_id` smallint(5) NOT NULL AUTO_INCREMENT,
  `album_name` char(128) DEFAULT NULL,
  `album_cover` varchar(1000) DEFAULT NULL,
  PRIMARY KEY (album_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
 
CREATE TABLE `artist` (
  `artist_id` smallint(5) NOT NULL AUTO_INCREMENT,
  `artist_name` char(128) DEFAULT NULL,
  PRIMARY KEY (artist_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
 
CREATE TABLE `played` (
  `artist_id` smallint(5) NOT NULL DEFAULT '0',
  `album_id` smallint(5) NOT NULL DEFAULT '0',
  `track_id` smallint(5) NOT NULL DEFAULT '0',
  `played` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
 
CREATE TABLE `track` (
  `track_id` smallint(5) NOT NULL AUTO_INCREMENT,
  `track_name` char(255) DEFAULT NULL,
  `artist_id` smallint(5) NOT NULL DEFAULT '0',
  `album_id` smallint(5) NOT NULL DEFAULT '0',
  PRIMARY KEY (track_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

The bashscript can be automated via crontab (example runs every 2 minutes).
