6 retro things only 90's kids will remember

I am a kid of the 90's. I still think the 90's music is amazing especially compared to the crap songs of today. But the 90's are much more than music. The 90's have its own lifestyle and some special things that only 90's kids will remember... I have chosen my personal retro top 6:

#1
Discman

MP3 was not even invented... 1 CD spinning in your discman. I don't exactly remember how many songs fitted on one CD. But compared to today... let's say really few.

36 Photos

...there were no digital cameras in the 90's. 36 photos was the way to go with you analogue camera.
