I like Broadway musicals like West Side Story, Sweeney Todd, Avenue Q, Sound of Music, Les Mis, The King and I, Passion, How to Succeed in Business Without Really Trying, etc...etc...etc...
Don't go on a long car trip with me buddy boy... you will regret it!
Personally I like folk, jazz, classical, Celtic/other traditional, and parody/comedy (like Weird Al, Ray Stevens). I like almost anything, with the exception of rap, hip-hop, ANY FORM OF METAL, and pop. But as I said to each his own.
I don't mind techno, haven't heard of electro so I can't judge. Techno isn't one of my favorites mind you but it can be tolerated for awhile, usually a short while.
