# Create a Song Smart Contract

> Create a Pay-For-Access (PFA) smart contract for a song on the blockchain

Create a PFA (Pay-For-Access) smart contract for a song on the blockchain. PFA stands for "Pay-For-Access". It represents a song that is available for sale on the SHARE protocol. Unlike NFTs where ownership of a collectible is transferred, PFA contracts grant users access to content while keeping ownership of the contract with the creator, similar to mechanical royalties.

## Song Contract Example

To create a song contract, set the `revenue_source.product.type` to `"pfa"` and include `pay_for_access_metadata`:
