The artist who sold their music for $100 million is not explicitly mentioned in the question, so it is necessary to gather more information or context to provide an accurate answer. However, there have been several notable music deals and acquisitions in recent years, so I can give you some examples for reference:
1. In 2018: Scooter Braun's Ithaca Holdings acquired the rights to Taylor Swift's music catalog for a reported $300 million.
2. In 2020: Hip-hop artist Kanye West claimed that he was offered a contract that valued his music catalog, including publishing rights, at around $9 billion, although the deal did not materialize.
3. In 2020: Bob Dylan sold the publishing rights of his entire song catalog to Universal Music Publishing Group for an estimated $300 million to $400 million.
4. In 2020: Hipgnosis Song Fund, a music IP investment company, acquired the music catalog of Neil Young, Lindsey Buckingham, Jimmy Iovine, and other artists for approximately $300 million.
As the question lacks specific details, it's essential to clarify which timeframe and context are being referred to in order to provide an accurate answer.
