After supporting an artist by purchasing one of their NFTs, you have the ability to make a public comment on the song that proves you were an early supporter. If you sell the NFT, your comment is replaceable by the new owner. Holding an NFT also gives you early access to listen to new music from that artist as soon as they upload. Aside from the comment feature and early listening access, Sound also offers holders access to gated Discord channels.
Artists that release on Sound can also include additional rewards for their collectors, which can be found on their respective collection page on Sound.xyz. For these rewards, the responsibility falls on the artist to deliver.
If you have reached out to the artist and they haven't responded within a reasonable amount of time, please reach out to us so we can help connect you two.
