Kind of a moot point these days, but I always wished OGG pushed MP3s out of the way. It generally has better audio quality, lower file size, and is an open source format. MP3s had their patent die (I think) and file storage has become less of an issue, but damnit OGG was perfect for the 00s. My plex server is still full of OGGs (I can’t hear the difference with uncompressed, but my hearing is bad).
