If you really care about Facebook likes, don't just post your stuff to Twitter and then rely on it being republished automatically to Facebook. In my sample size of one, Facebook penalizes you significantly for that and shows that content to far fewer people.
I've never been one to think it was cheating to sample this or to loop the drum part there - I've always done that. Even using four-track cassette recorders, I was always doing whatever I could to make it as good as I could.
I think people who sample are cheating. It is like people who do collages. Use all of your own stuff.
I've been around a long time, and when I was at the top of the hill, I was very ahead of my time! Evidence of that is that my music is still current today - you know, rappers sample it all the time. So, rather than compromise my artistic integrity, I concentrated on movies.
If you aren't taking a representative sample, you won't get a representative snapshot.
