I really try to use a real variety of different records cuz i believe itll slowly help me develop my style or signature if i start to see a pattern even though theres different kinds of music involved. But id hafto say my favorite genre(s) are probly Classical/Male Opera (nawmean, 1920's gangsta music)/Piano Masterpiece/Easy Listening. It looks like a lot on paper, but they really fall almost into the same category. But got like 3 or 4 crates of dope shit of just these styles.
Any and everything even though I'm not a sample producer as of yet. But I do understand the work the goes into crate diggin/listening and I know you have a fantastic ear to get that hot sample.
Anyway when I do start, which will be sometime this year, I will look to any source. Movies, commercials, cartoons.
