Not “most people” - pros on high end equipment cannot pass an ABX on 256kbps MP3. Spotify’s “extreme” quality setting is 320kbps.
This isn’t some “normies”/“audiophiles” thing. 256kbps mp3 is acoustically transparent to human beings in ideal listening situations.
The bad rap mp3 got was from 128kbps that was more common pre-broadband.
Also, using lossy compressed sources (even 256-320kbps) in derivative works (eg dj mixes, samples, et c) that will be later lossy recompressed (podcast, satellite radio, spotify, et c) is a good way to make your production sound crappy, which is why lossless is important. Any audiophile who tells you they need lossless for final listening simply hasn’t tested it. It is religion, not engineering.
256kbps MP3 is transparent in most cases, but there are some sounds that MP3 is bad at encoding (notably the sound of maracas and similar rattle type sounds), and you can train yourself to get better at identifying MP3 artifacts. People have reported successful ABX of maracas sound at 256kbps, e.g.:
Everyone gives this pitch, but I alwast spot the teltale digitl diatortion immediately. It affects the transients. We are training ourselves to hear worse.
I disagree. I can often tell the difference between CD audio and 320 or v0 mp3s. I can also notice compression on files with a lower bitrate than 320 or v0.
You can really notice the difference on the high end and the width of the soundstage.
