OK, maybe not you on the Apple, that was more for Deepster.
I get the "I love radio" part. I just don't feel that way in 2021 as it's been so long since I've heard decent radio. If you can convince me that there's another "Idiot's Delight" out there, maybe I'd change my mind.
As far as Pandora's algorithm goes, I found it weirder and more eclectic than Spotify, even though the latter has a much larger library. My Lyle Lovett station is a trip. All sorts of weirdness there. I've got 15 or so stations, some based on specific songs.
I particularly enjoy my "Kelly's Heroes" (Black Grape) station (as an aside, I'll argue with anyone that "It's Great When Your Straight" was the best album of the 90s). I just put on whatever I'm in the mood for and I'm good for a couple hours, or if I'm feeling wild, there's always shuffle.
You'll find this amusing. While my channels represent a number of genres (none of them Van Morrison), pretty much all of them eventually land on one or more Van Morrison tunes.
