I have this with some albums. Is this something to worry about or is this normal? Or am I missing out on something?

2That looks like it was just re-encoded from something at a much lower bit-rate & what you are seeing are odd ghosts of lower frequencies, I'd guess an encoding error. As there's nothing musically useful up there anyway & few people over 18 can even hear 20KHz, if you can't hear it, don't let it bother you… & don't be fooled by supposedly high frequency audio files unless they come straight from the studio. – Tetsujin Jul 31 '20 at 16:04
