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.

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,

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