Better questions indeed.
1. There are truely loads of articles on the blog and posts on the forum about how to build a good collection. I suggest you search for a few of those.
2. I take it as a sign he really doesn’t care what I play as long as the crowd is happy. So, I play, watch the crowd reaction and build from there.
3. Not sure I understand this question. Making beats as in creating your own tracks? That would be producing and I can’t tell you too much about that, but am sure others here can. Finding beats? What exactly do you mean.
