I did several single-blind tests where my wife would select either an AAC 256, MP3 320, or lossless FLAC file using YouTube Music, Tidal, Qobuz, and/or Amazon HD music and I'm usually able to get about 9 out of 10 right when comparing lossy to lossless. First I listen for little echos, ticks, or other sounds that come from the musicians, their instruments, or their voices. If I can't find those then I simply clear my mind and ask which sounded clearer. To do this reliably I have to use headphones. I can't do it with speakers, but maybe my speakers just aren't good enough
