Think of your NFT like a special collectible card. Both the cover and the audio of your Collectible/NFT (the media) and its details (metadata) are stored in a digital library called IPFS. Meanwhile, the unique certificate that proves it's yours is kept on the Ethereum network, using something called an ERC1155 token. So, while the art is in one digital place, the proof of ownership is in another. Both are super secure and are linked together to make sure your NFT is safe and truly yours even if Winamp went to disappear.
