CDizz

CDizz is based on the idea that audio CDs should offer more than music.
The CDizz Player adds dynamic content to Audio-CD titles. CDizz can turn
ANY CD into a multimedia experience.

The CDizz Player uses legal, purchased CDs as a key to download CD
specific content: Images, Lyrics, Karaoke, Slideshows, Coupons, News,
Guitar Chords, Animations, Pops and much more.
