Startup JKBX has launched a new platform that allows investors to purchase shares of royalty streams from popular music artists such as Beyoncé, Taylor Swift, and Adele. This innovative approach to music investment, reminiscent of the 'David Bowie Bonds' concept, has received official approval from the SEC.

However, there is a catch to this investment opportunity, though the details of this caveat were not specified in the provided information.
