In music, that is.
The four contenders are:
Vinyl
Cassette
Compact Disc
Or - gulp - DOWNLOADS!
My favourite is vinyl and as I type this I'm playing a Roy Orbison 33 1/3 on my turntable and having a good foot tapping time.
My second favourite would be compact disc purely for the longevity, third favourite being cassette and the last, well, I'm not even going there.
What's yours?
