In the late 90s, I was at a party and the DJs were playing really cool techno styles I hadnt heard before. (back then it was about Sample-CD & soundsets, Gigasampler etc., all that stuff)

Curious as I am, I asked him what sets he used for his samples - he said: I can highly recommend all these Office-Clip-Art CD samples, because they are not used by a lot of people :-D
