So I find these videos pretty helpful, I figured I'd put them all in a playlist so there's more information in one spot rather than having to look it all up separately.
I was able to make this (with some help) with stuff I learned off of these videos.
A couple of tips on finding samples,
Movie soundtracks from the 60s-70s are usually pretty good for finding loops, I've had luck with twilight zone, dirty harry, and fist of fury. Any flick with a jazzy soundtrack should work. And you can also take vocal snippets, from movies or even just YouTube videos, to give your beat a little more meaning.
(If anyone has any more useful information, feel free to share below)
