Basically just what the title says. I already went ahead and removed youtube reference links with Kocka's approval (and bringing it up quickly on the discord) for reasons explained in the edit summary. I also wanted to remove the similar samples section. Samples aren't motifs, they don't have thematic relevance and one sample can be used in dozens of songs just because it happens to sound good. It'd also be basically impossible to list them all.
I was just going to do this, but I figured removing a whole section without at least making a discussion post for the record wouldn't be the best, so I'm making this first. I really don't see any reason why it should be kept though.
