That is basically what I do, except it would be nice to have Roon do some of it for me and to remove podcasts from the album display, etc.
For what it’s worth, I use a simple command-line downloader called Mashpodder that works on MacOS and Linux (and perhaps on Windows, with the Linux subsystem or the like). I am considering transitioning to a similar but more advanced client, greg, that also works on MacOS and Linux. If I were starting out today, I’d definitely go with greg, to take advantage of its tagging features.
