Most of Sinatra's "ballads" and torch songs. Say what you will about him, his phrasing and orchesteral arrangements were, to my ear, always spot-on; Bob Shane's "Scotch and Soda" (yep-gotta get a KT song in here-LOL); These days my ears are turned by the clear, rather crystaline female vocals of someone like Alison Krauss, or Sara McLaughlin--even though the tunes need not have ANY kind of romantic/sexual content-they just make me want to curl up with them in front of a roaring fire and some fine wine. Sorry if that sounds dumb. And I'm sure plenty of you can't stand the two examples I cited.

What I DON'T find "sexy" is the Britney Spears/Jay-lo/girly gyrations and scantily clad females appealing to the pre-pubescent teen female (or male) market.

I'm also with the "crew" that finds "best" or "most important" lists impossibly subjective, and usually spread more heat than light. My opinionated 2 cents.
