I concur. I've been hesitating to post too voluminously about audio on a thread initially about the magic of the continued usefulness of old HTML pages, but since a few people have been welcoming my side-journey to audio format longevity...
Yes, I concur with @thomasfuchs about the usefulness of FLAC. It's unsurprisingly the format I've standardized on for PCM audio–offers a useful amount of compression while being lossless, includes good tagging support.
