Many years ago I laboriously ripped a collection of CDs (and a few cassettes) into digital files. It was already clear at the time that I wouldn’t want to lug discs around and that these newfangled “MP3 players” were on to something good.
Unfortunately, the hard drive space required to store my collection in a lossless format was far out of reach for me at the time, so I resigned myself to keeping everything as lossy low-bitrate MP3s. Later, a new free/open-source and patent-unencumbered format called Ogg Vorbis turned up on the scene, and my enthusiasm for it overpowered my horror at re-encoding from one lossy format to another, so I gritted my teeth at the quality degradation and converted everything.
Now in the present, Vorbis has been surpassed by Opus, FLAC exists, hard drives are cheap, and it’s time to start over.
