Any question answered...

relatedly - does anyone have recommendations for a custom vinyl record maker?
also, will they only do original or copyright/licence held stuff, or can I get a "mix tape" record?
I'm assuming it's not actually legal to make mixtapes even from music one legitimately owns :/

Do you want to dj it or do you want to have a longer lasting proper record? You could get acetates done if you were playing out somewhere but if you want proper vinyl search for small run pressing. I reckon they'd press whatever and not care about copyright. It's loads cheaper over here than in Oz (not that you care) and there's probably some continental options worth looking into if you want more than one pressed.
