Global Playlist Management for On-chain Radio Station

As a user, I want to be able to submit songs to a global playlist and influence the play order by making payments in ETH, so that I can share my favorite music with the audience and have it played according to my preferences.

Acceptance Criteria

• Users can submit songs to the global playlist by paying a specified amount of ETH.
• Users can pay an additional ETH fee to 'skip the line' and have their song played earlier.
• Users have the option to pay ETH to remove a song from the playlist.
• The system will validate that sufficient ETH has been paid for the requested action before execution.
• Users can listen to the on-chain radio station directly through the website or through an embedded player on other websites.
• The system keeps a transparent ledger of payments and song queue changes on the blockchain.
