Sampling Ethics

I feel that sampling without any permission from the original artist or producer is unacceptable. I feel this way because when you sample a song or a movie it is like taking pieces from something and copying it. If you ask before you use the piece, I feel that it is okay because the artist or producer is giving you consent to use there piece of art. Just this past weekend, a artist named Lil Uzi Vert got his song taking down for copyright. So, with that said always ask for permission before you use someone else’s art.
