It is the responsibility of the uploader to ensure that all of the proper clearances & licenses have been secured when distributing a cover song or a song containing samples.
If you have recorded a cover song, you must obtain a license for the underlying composition. Stem has partnered with Easy Song Licensing to help our users obtain the proper licenses. Reach out to your account manager for more details.
If your music contains samples, please forward your proof of clearance to your account manager prior to distributing your music.
