> unless you go to a source like Qobuz which serves FLAC. Apple is another odd one out there by only selling music as AAC, and Bandcamp gives you a comprehensive choice of all sorts of formats. > Same with devices - basically everything supports MP3. Vorbis and Opus support is far patchier. True that, though AAC support might also be somewhat reasonably common-ish these days. (Though I've found that apart from also having a relatively low folder count limit in general, my car radio also has some difficulties with reading the metadata in some files, and as far as I can tell I think the affected files are all MPEG-4 files. It's only some MPEG-4 files that are affected, though, but I haven't yet bothered to find out what exactly else they might have in common.)
