Which of the following is a music asset type?

A Composition Share is a music asset type in YouTube's Content ID system. It represents a fractional ownership or rights claim on a musical composition, allowing rights holders (like publishers or songwriters) to manage and monetize their portion of a song. YouTube's rights management tools are designed to handle various music asset types, including sound recordings and compositions, to ensure proper attribution and revenue distribution. "Web," "Movie," and "Television Episode" are not music asset types; they are broader content categories or media formats that may contain music, but they do not define a specific type of music asset within YouTube's rights management framework.
