I care, because I’ve been using streaming media for quite a few years years and not kept up with any changes

Well, most of my music collection lies as mp3. I care about metadata and all of them have tags. I would love to convert my collection to opus but first I need FLACs and an easy way to move over metadata, since vorbis is different than ID3tag. Do you know a streamlined way for this?

I am very slightly annoyed that people haven't moved onto Opus which gives you better compression and quality than MP3. MP3s are still useful for any older devices that have hardware decoding like radio sets, handheld players, etc. Otherwise, every modern device should support Opus out of box.

Hilariously, x264 has the same problem where there are direct upgrades with H.265 and AV1, but the usage is still low due to lack of hardware accelerated encoding (especially AV1), but like everyone uses FLAC for the audio which is lossless lol.

I use m4a format simply because my downloader uses that format. But I think m4a sound quality is better than mp3.

My music folder is 40GB of MP3s. To this day I use an online YouTube converter to collect music.

Yeah my car plays the 11,000 MP3s from a SDcard inside the armrest compartment.

Mp3 has been dead to me for nearly a decade. Flac is superior in every way.
