All the songs I have copied to iTunes get uploaded, but if you have the lossless versions they get converted to normal quality on other devices, or if you remove the local original copy.
Music doesn’t support flac, though, you have to convert them to alac first.
I also use a Mac, I don’t know if it’s different on windows
I do this on Windows, it works fine. Never had an issue with mass uploads / initial library sync. I have a large library of 30k tracks, mostly lossless ALAC.
I switched to Plex / PlexAmp though, it’s better and I don’t have to pay a subscription.
I wonder if you can get around that by altering the metadata on the local files to make it a slightly different version of the same song. The deluxe album version vs the regular, etc.
