Here's the deal - some songs I like, some I don't. In either case, I may or may not categorize the songs into categories - folk, blues, jazz, classical, calypso, gregorian chant, show tunes, rap? (Listen to Oscar Brown - Bid 'em In or Man, Earnest Boy for circa 1960 rap), etc. Now, while I've spent most of my life listening to and playing music, I ain't no scholar. Sure, I've read tons of books and articles about musical subjects that I wanted to find more info/history about. But, again, this exercise may or may not add to my experience when I hear/play a song. I like songs that make me feel - joy to pain and everything in between. Once I take a song into my soul, it is, for me, a folk song. So, I guess that includes just about everything. Ok, Ok - we'll leave Stairway to Heaven out (grin).
