Thanks - very helpful and gives me a few new ideas. I've always used %album artist% to include band members and overlapping projects, but I like your direction.
Thanks everyone for your feedbacks! What codecs do yall use and at what bit rate?Lossless for to keep - transcoding to two-figure bitrate for on-the-road. Opus because it impressed me ... and because artists don't use it much for free downloads, so by using Opus I "know it is my own transcode", and those files are disposable.
I can hear frequencies above 20KHz, confirmed by ABX, with and without 20KHz lowpass.
