Among the notable aspects here...nearly all of these allow, if one pops out the links to watch/listen to them at YT, track selection.
Also notable, perhaps, is that these key albums of the Byrds' and Beatles' careers are also their jazziest albums...for the Byrds, not solely "Eight Miles High" and "I See You" but even "Hey, Joe" feature heavily jazz (most obviously John Coltrane)-influenced guitar riffs on McGuinn's part, and McCartney reaches toward pop jazz in "Good Day Sunshine," "For No One" and particularly "Got to Get You into My Life," and while the tape loops and other experimentation running through "Tomorrow Never Knows" owes more to post-serial electronic music innovators in the classical world, that and some of the other Lennon songs (and Harrison's playing around with Indian classical influence) all have a certain free jazz flavor to them (not quite the MC5, but along the path). Perhaps some of my fondness for these stems from the Wailers being essentially still a ska band, moving toward the creation of reggae, and that the Animals, the Stones, and of course the Yardbirds, while growing more adventurous, were still not quite ready to shed their partial identities as blues bands...
