It didn't really take, but there are some pieces I really liked, such as "Rite of Spring", Vivaldi's Four Seasons, "Hall of the Mountain King," "Fur Elise", "Take Five," etc. Jazz is just too abstract for my taste. Classical deserves more investigation, but too much of exploring it feels like homework.
I know that BD lives in Kansas and has a natural allergic reaction to roots music due to overexposure to redneck culture, but a lot of great new (well, to me) music is reaching back to what Greil Marcus called "the old, weird America". I've long since worn out modern rock bands, but I've had a great time exploring stuff like Lefty Frizzell, Jimmy Rodgers, Leadbelly, Howlin' Wolf, Louis Armstrong, Billy Holiday, Ella Fitzgerald, Woody Guthrie, etc.
Have you heard Louis Jordan yet? The first time I heard him, "Where has this music been all my life?" The surest guy to put a quick smile on the face.
