Kpop Sample
The artist or agency secures the legal rights to use the original audio recording (sampling) or re-records the melody themselves (interpolation). Copyright holders are credited and paid royalties.
If you hear a weird instrumental intro in a Kpop song that doesn't sound like Kpop, isolate that 10-second clip (using YouTube isolation tools) and run it through Shazam. Shazam might identify the original sampled song instead of the Kpop cover. kpop sample
