Introduction:

(missing time see comment in ISRCRegistry for AllTunes dapp):

• @notice this contract is intended to serve as a registry of listening rights to any sound when an ISRC is bound
• @notice thus any music player can broadcast music to a user according to his rights
• @notice any dapp can connect and a user has a 'universal' right to listen to whatever the player
• @notice 2 possible mode for user : PRIVATE or PRO
• @notice a private user can buy a lifetime rights (as if he'd bought a song in a store) or pay a subscription for a short time (rent)
• @notice NOT YET ADDED TO THE POC (due to loss of time with bridge project on allfeat) :
• @notice a pro user should fund a subscription vault giving access to a limited time to play use the song
• @notice a way to pay in usd equivalent token. The bridge will allow this
• @notice an oracle and dex to swap tokens and be abble to accept more tokens to pay
• @notice an oracle to fetch ISRC data from ISRC agency database to validate a code
• @notice IMPORTANT think about storage => huge amount of song and user can increase a lot the storage
• @notice test and study needs
• @notice a solution could be to have a main resolver contract allowing to have a "pagination" mechanism with child storage contract

following the first hackathon we see the need of a bridge for the crowdfunding dapp. We decide to make it functionnal for this hackathon dapp as we need stablecoin to pay.
