Hi Andrew,
Thank you for using continuously TuneBrowser. (^^)
I also have a multiple INDEX CD. It is an early version of Glenn Gould’s Goldberg Variations (1981), which has only one track and 32 additional INDEXes. But this CD is very old and I have already bought a new CD and usually listen to the ripped version of the new CD.
Of course there are people who still listen to these old CDs, but I think that many of them have switched to the newer material like me.
So, I think the need for multiple INDEXes is small…
