I enjoy music of all types, though do I have a special fondness for "classical" music (symphonic, orchestral, chamber, and choral music), and I'm an unrepentant fan of Broadway musicals. Some favorite artists include The Beatles, Queen, Billy Joel, Elton John, and Sting. I'm also a long-time fan of Enya.
I also enjoy making music: over the years I've been a member of various singing groups, including the Harvard-Radcliffe Chorus, the Caltech Glee Club, and a kick-ass pop-rock a cappella group called Ecphonema (from an obscure Greek word meaning (roughly) "a loud crying out").
Here a couple of music lists, sort-of in order.
(My apologies to Jeremy Martin, who, if he ever sees this list, will never forgive the omission of Johannes Brahms.)
*This list really should have a separate entry for "everything Mozart ever composed".
