I am also underwhelmed by radio.
As a a represenative example of what I see, I seeded with Lisa Hannigan, ‘O Sleep’. She could be fairly categorised as guitar accompanied female Indie/Folk and guitar accompanied female Indie/Folk with a couple of exceptions is exactly what I got. Laura Marling, Feist, Julia Stone, Lucy Stone, Bat for Lashes, Emilliana Torrina, Aldous Harding, Beth Orton, Cat Power, Daughter, Marissa Nadler, Lara Viers.
Radio then repeated with exactly the same artists (different tracks), in more or less the same order. It was then ‘broken up’ with 3 male Indie/Folk tracks (but very similar) from Bon Iver (contralto vocals?), Villagers (also Irish), Damien Price (with whom Lisa Hanninigan partnered).
It has subsequently gone back to Lisa Hannigan and the same group of Indie/Folk female vocalists although it is breaking it up infrequently with male vocalists like James Vincent McMorrow, Noah and the Whale, and Beirut.
What surprises me more than anything is that although all these picks are from Qobuz I have, so far, all of the artists locally and most of the albums. So not only is roon not really showing me anything new, it is not breaking up the play list with fast/slow, other related genres or artists not in my library. I rather suspect that the reason why I have all of the artists and most of the albums in the first place is that I have already added the gaps in my library from previous listening sessions. This may explain why there are so many mixed messages about roon radio. I for example, was initially thrilled with roon’s picks but with repeated exposure the novelty has certainly worn off as roon is not able to consistently repeat the trick of surprising me.
This is not necessarily a bad thing under certain circumstances. It is certainly setting a rather consistent (though monotonous) mood and this is probably why I tend to use radio when we have people over and I don’t want to think very much or for there to be any surprises. But in terms of ‘discovery’ radio isn’t really doing anything for me and I notice that I use it less and less.
