Itheum is a web3 data protocol on the Layer 1 MultiversX blockchain (https://multiversx.com/). We have a music app called NFTunes that allow musicians to trade their music as "Data NFTs". Currently, on the MultiversX blockchain you can need to buy the Data NFT to listen to music, we have been asked to look at “pay-per-music-stream”, where listeners can pay micropayments to listen to music rather than buy an entire Data NFT. We are looking at using Lightning for this feature.
