/**
 * @dev This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed
 * behind a proxy. Since a proxied contract can't have a constructor, it's common to move constructor logic to an
 * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer
 * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.
 *
 * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as
 * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.
 *
 * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure
 * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.
 *
 * [CAUTION]
 * ====
 * Avoid leaving a contract uninitialized.
 *
 * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation
 * contract, which may impact the proxy. To initialize the implementation contract, you can either invoke the
 * initializer manually, or you can include a constructor to automatically mark it as initialized when it is deployed:
 *
 * [.hljs-theme-light.nopadding]
 * ```

// Jason DeSante

//
// New in v2: custom max supply,

// Rarity affected by generation of copy
// Added public mint switch (staking to the store) as an option to mint copies traditionally.
// Added recycle to burn 2 songs to mint 1. Recycling is an opt in option.
// Added promo system. Supports ERC721 tokens, and 721J support letting you set promos with rarity and songId. Each promo has it's own price multiplier.
// Added and the ability to change the max editions of a song, the name or symbol of the contract.
// Added a rarity price multiplier to make the price different for specific rarities.
// Added support for splits, each song can send it's tokens to a specified address.
// Added support for IERC-2981, and on chain royalties.
// Added 4 interfaces to represent the essential functions in 4 main pieces of the 721J
