Roon is also a music magazine, allowing you to get overviews of musicians, look at album reviews, discography, link to performers in the band and other bands, all the data there while you listen to the album. https://www.youtube.com/watch?v=q7qBMeTJWAQ
It also provides a sophisticated digital signal processing which IMO is worth the price of Roon alone. https://www.youtube.com/watch?v=CU-wLZDN4CQ
