If you need to transfer it to your record label or another party please contact support@tracklib.com and we’ll send you a novation agreement to fill out. Once this is approved and signed by us and the new license holder, you’re all set.
You can also send your song to another user/label/artist - if you are not the one who should be responsible for licensing the new song. You can easily do this by simply click the button "Send song" at the top right corner on the 'Your songs' page.
