Last week, a music producer with ties to Rihanna dropped a collection of 300 royalty-linked NFTs ahead of her Super Bowl LVII Halftime performance. The small collection of NFTs were made available for purchase last week at $210 per NFT and quickly sold out.

Each NFT provides holders with royalties from streaming revenues of her 2015 hit song, “B**** Better Have My Money,” and includes some other digital goodies.
