It may be better to stay away from samples unless you have written permission from the owner(s). If you do have permission, you can upload music with samples but you must connect all rights owners with correct percentages of ownership before the song will be discoverable.

If it is a remix of your own song however, you are able to distribute it!

Important Notes:

• Without approval, you cannot distribute a remix of another artist's track.
• If you want to sell a song that contains samples, you must be certain that those samples are royalty-free and cleared for use, including securing permission from the copyright owner(s).
• Be prepared to present artist agreements and/or proof of permission to Songtradr support in order to validate the distribution of the remix.
