As a friend of mine put it, I have the world's weirdest iPod.
My music collection runs the gamut of musical history. I have classical (Bach, Beethoven, Tchaikovsky, Mozart, Mendelssohn, Chopin, Vivaldi and some others), jazz (Miles Davis, Chet Baker, Count Basie, Ella Fitzgerald, Gershwin, and some others), quite a bit of Sinatra (le sigh), a ton of Billy Joel, show tunes from Phantom of the Opera, Gypsy, West Side Story and Rent, and even some Led Zeppelin. I also have quite a few Jewish artists, ranging from the great cantors Yossele Rosenblatt and Moshe Koussevitsky, to modern-day Matisyahu (who I never looked at the same way after he played a concert on Shiva Assar B'Tammuz). It's a little of everything--kind of like me.
