Yep ...
Radiohead thought floppydisc was going to be how we were going to listen to future recordings when they released OK Computer in 97.

that was only TWENTY YEARS Ago!
Other progressing roads were faced at that time too -
for example, I bought a few commercial mini discs as I thought they were going to catch on - really great sound, but alas not enough popularity outside of musicians interested in recording themselves ....
So, if we sum up the progress of recorded music from the old LP 78 and the music cassette in the 70s and the 80s, are you astounded - like me - at the so rapid progress of late?
And where will this lead us in another twenty years?
Please share your thoughts!!
