Though, keep in mind, you'll need to purchase the cover license again for the cover that is being included on the album.
You must purchase a DistroKid cover license each and every time you upload a cover song to DistroKid.
If you upload the same cover song twice, you need to select the “Cover Song” option both times, essentially buying two licenses. That’s how our system knows to deduct the songwriter’s share of earnings from your earnings (for both uploads of that song, in this example). Furthermore, DistroKid licenses apply only to content directly distributed by DistroKid, and cannot be used for any purposes outside of DistroKid.
It is your responsibility to ensure that your song would be covered under the compulsory mechanical license.
