Implement Subscription System for User Access
Description
Currently, the contract handles song ownership and transfers but lacks the core subscription functionality described in the platform requirements. We need to implement a subscription system that allows users to pay Stark tokens for platform access.
Requirements
- Create subscription management functions
- Track subscription status and expiration for users
- Handle Stark token payments for subscriptions
- Implement subscription renewal functionality
New Functions to Implement
fn subscribe(ref self: TContractState) -> bool;
fn check_subscription(self: @TContractState, user: ContractAddress) -> bool;
fn set_subscription_fee(ref self: TContractState, new_fee: u256);
fn renew_subscription(ref self: TContractState) -> bool;
