I wasnt so much thinking about samples from things like the beach boys or clint eastwood as I was thinking about people who sample other techno tracks to make their own techno tracks - think ignition technician as a prime example. They may well clear their samples I dont really know, but there are plenty of things that get released with that sort of sampling in them, that dont get cleared.

Anyway its just a thought I had, I dont really care that much, as I said I've sampled all sorts, and dont really care about clearing it, but one thing I will say is I've never sampled another techno track, all my samples come from other genres of music, and the artist will probably never know, so I dont really care.
