pop will eat itself

I got a surprise listening to this track:

So... who copied whom here? I'm in the dark here.

P.S. Listening to more BTB I'm hearing a lot of the same samples PWEI used in that era.

I'm pretty sure PWEI sampled the Beat Dis beat for the original Def.Con.One, I think PWEI recreated it for the 1989AD version though.
