The Walkman was the cassette player. Weren't the CD players called the Discman?
Now I'm sad that I'd lost my Walkman more than a decade before that, in or around 1990. The Discman sounded better, but was worse on batteries and skipped if you looked at it funny.
Same for me. I was rocking out to Cinderella, Scorpions, and Poison on my Walkman and then it sounded better later on the Discman with no need to flip or rewind for the specific songs.
First ones were branded "Discman" for some reason before Sony went back to using the "Walkman" name.
I find it weird since all of the other portable stuff before and after like MD, DAT, MP3, and the newer hi-res players were released under the "Walkman" name
