CD vs MP3 Sound Quality Measurement: See How Big the Gap Is Between CD and MP3

First round of tests: listening to the same song for the first time

When the CD was just put in, the sound inside had a special flavor, and the CD sound was particularly clear. My first impression is that the sound of the MP3 is a little different, after listening to a song, I feel that the sound quality of the CD is very good.
At first, I thought that the sound quality of the MP3 is a little worse than the CD, but when the MP3 plays the same song, it has a clear taste of the CD version. My feeling is that the sound resolution of MP3 may not be as high as that of a CD. I listened to it because I listened to the CD first and paid attention to these crisp sounds.
Second round of tests: listen to it several times
When I listened to the CD for the second time, I found that the resolution of the CD is not much higher than that of MP3, and the sharpness of the sound is similar to that of MP3.
When I listened to MP3 for the second time, I felt that MP3 was similar to CD, and I felt that MP3 was as pure as CD. Could it be that what I heard before was an illusion? I don’t know if the ears assimilate or what, but it feels very close, and the CD isn’t that far ahead of the MP3.
After that, I listened to it many times, and always wanted to hear the difference, but the more I got to the bottom, the less I could hear it, it felt like CD and MP3 were almost the same.
The third round of the test: listen to one of the lyrics and a piece of music
Listening to the lyrics and music on the CD is particularly clear, and I paid special attention to some points. After listening to the lyrics and music released by MP3, I can feel that the CD is a bit better.
After that, I have listened to it several times and I can feel that one of the lyrics and one of the music on the CD is a bit better than MP3 in terms of sound quality. However, I made some mistakes during the period, that is, I did not pay attention to listening sometimes and I did not hear the difference. Because of this bug, I thought of another question, should we all pay attention when listening to music? Is it as serious as playing a game? If you listen like this, can you still enjoy the music?
