I wouldn't even bother with MP3 in this day and age, you might as well just use uncompressed formats as storage on devices these days is huge.....20 years ago it made sense when a lot of us were still on dial up internet with 56k speeds and had computers with 1gb hard drives. Now, even my phone has 512GB of storage and my laptop 1.5TB. The only thing stopping MP3 becoming obsolete is that there is so much legacy music still sold in MP3 format, as that's what it was ripped to 20 years ago.
