If you use a Shroom composition sample on a track you will split everything (credits, publishing, royalties, advance etc) with Shroom.
Drums and Breaks are Royalty Free
You may not sublicense, sell, loan, share, lend, broadcast, rent, lease, assign, distribute, or transfer any Sample to a third party except as incorporated into a Recording
On most smaller independent projects clearance won't be necessary and you can just use the sample/break however you like.
Please reach out to shroom@producedbyshroom.com or matt@dreamville.com to see if clearance is needed and/or to work out the details.
