Final answer:
When an artist releases an album independently featuring songs they have written, they are not required to pay any mechanical royalties.
Step-by-step explanation:
When an artist records and releases an album independently that features songs they have written, they are not required to pay any mechanical royalties. Mechanical royalties are paid by the person or entity that covers and distributes the song, such as a record label or streaming platform. Since the artist is releasing the album independently, they have the freedom to negotiate their own royalty rates or retain all of the rights and royalties for themselves.
