Yes, you can use samples in your tracks. However, just like with any other material owned by third parties, using samples requires proper licensing.
During moderation, our platform uses automated content recognition tools along with manual checks of each new audio. If your track contains borrowed fragments, you'll receive an error notification asking you to provide a license for using that content. In that case, you'll need to send the license to the address specified in the error message.
We strongly recommend using services like Tracklib or Splice, which offer pre-cleared samples. These platforms provide licenses for samples, making the process of legally using them in your tracks much easier.
