@retronianne@tech.lgbtI queried everyone with the intent of trying all the suggestions and reporting back. Two folks (and several others afterwards) immediately suggested Quod Libet as their favorite. So I started with it.
Y'all.
With a number of track layouts, an EXCELLENT tagging system, and deep configuration changes with a number of plugins, this might have pegged my wants in one. It's good.
I'm still going to try the others suggested...but they have a high bar to clear. Quod Libet (I know...I don't like the name either) is really good. :)
