Sampling music has always caused a little bit of controversy in the music industry. I see this happen a lot and I’ve done it myself. People takes snippets of old, maybe new songs, and form their own sound or version of that song. I think you should make the sample sound completely different from the original version but it’s all preference. I believe you should make it hard for people to pick it out so they wouldn’t even know where to go to find it. The controversy side comes with people saying “you must be lazy if you have to sample something” and it’ll probably stay that way. No matter what, don’t feel restricted by what people say. Express yourself in whatever way works best for you (without taking away from the artist on the sample).
