>>74721338Almost* nobody can tell the difference between lossless and 320kbps mp3 or its equivalent in double blind tests. It is typically considered "transparent". You can usually see the difference if you open it in a spectrogram though. There's also the factor of most digital music not being mastered to take advantage of those extreme frequencies, which means there wouldn't be a difference in the first place.
*Some very rare people with exceptional hearing might be able to.
Imo just enjoy your music. If storing locally, get lossless since storage space is cheap, otherwise just use whatever's available.
