Sample whatever you want, especially non music related audio, if you’re streaming 7 million a month, make your label clear the samples, otherwise go for it.
Obviously don’t sample other musicians, especially in the same genre as you, be more creative!
Worse that will happen is you will get a cease and desist to stop selling, streaming, or performing that song you ripped off.
~Then you can sell your extra vinyl test press copies on Discogs because the “cancelled” song is now even more rare and famous from the controversy! Next it’s time to whore your remix skills to a major label and sell out, ignore the fact the underground will reject you when you come back groveling because your sound gets stale. In a year or two you’ll be a curious footnote on some music bloggers forum, ten years from now a rapper or country singer will ironically sample your track but actually have the copyright licensed and make a ton of money playing shows based on its popularity… well done you’ve just created the next Billy Ray Cyrus and Achy Breaky Heart will haunt humanity for the next century, torturing souls and making innocent children cry with pain when they hear it.
Don’t Sample!
