No conductor is not Roon. However, there are lots of ways to discover new music. A tab with all new albums, new by genre, there are thousands of internet radio stations. Conductor is well regarded and I I cannot say enough about its sound quality, the company, etc. I have no problem discoing new music. But it is not Roon.
I have used Roon. But I own two Aurrender because they are such great streamers.
