Even though I also hardly use ARC currently I think one of very important features is ROON radio which should make a valuable contribution to music discovery.
Unfortunately that is still far away from being „intelligent/smart“ - hopefully this gets adressed finally by ROON as there are also major problems for years (like How to get the best experience from Roon Radio? - #75 by armandhammer )
@danny hopefully has some input on the roadmap.
