My dad and I noticed something: On Michael Jackson's "Burn this Disco Out",there's a certain chord that occurs before the track fades out. That one chord sounds slightly out of tune (flat) to my dad and me. It's just that one chord in the entire song. One possible explanation is that it's from someone putting their finger on a turntable, as if the disco was burning out. Anyone notice this or knows something?
Also, on Michael Jackson's "Love never felt so good"featuring Justin Timberlake (Jackson was dead at the time of release), there's a trumpet hit just before the 2nd chorus that sounds slightly sharp to me (over the words "I can't take it 'cause"). The note should be C. Is this a reference to the earlier phenomena? Just before the 1st chorus, the exact same note is played perfectly in tune to my ears. Also, if it's not intentional, what causes this error? It's not the same recording equipment as was used for Off The Wall, I'm pretty sure. Also, considering that it's a brass note, is that a consequence of (say) live brass players simply not having perfect intonation on that note?
Can anyone at least confirm that there is or is not a slight difference in intonation? Can anyone offer an explanation as to why?
In both cases it's an extremely isolated incident that fixes itself a split second later, so it can't be because of the endings being out of tune. I still need an answer to this question; existing answers are inadequate.
