I have a rather old CD player (late 80's/early 90's) that does something quite interesting on at least two CD's I own -- Opeth "Still Life" and In the Woods... "Omnio". The LED window has, beside the normal track number indicator, a number to the left which says "INDEX" and is almost always 0. On these two albums, however, it actually changes with the song. See pics of "The Moor" playing:
Intro, guitars fade in, "index" is 1
Acoustic guitars begin, "index" switches to 2
When distorted guitars come in "index" switches to 3.
"299 796 Km/s" from Omnio works in a similar way. This indexing system probably exists in the CD specification as a way to index long pieces of music, but as no newer CD players I have ever seen has this feature, it probably never caught on. The question is why such new CD's as "Still Life" and "Omnio" would be encoded in this way then... Oddities.
