What does Firefly do with this replaygain metadata, given that it is doing the transcoding from FLAC to WAV for streaming to the Roku’s… ???
It tosses it. 🙁
I have it on the 1.1 roadmap to map the different gain info from each of the music types and store that in the db (and present it to an iTunes client), and there has been some discussion of doing what you propose, but I don’t have a fixed timeline on that. Probably will happen at some point, but after the db refactor.
