Perfect Soundtrack for Stylish Sunday Lunch?

As much as I love a wide variety of music, I seem to have great difficulty matching music while entertaining guests.

This weekend, I am hosting a lunch for a few couples, some of whom are visiting from overseas, and I really need to make a good impression.

Perhaps it is because I am more interested in sitting down and really focusing on music than having it in the background, I find this so difficult.

Things that immediately come to mind are usually pretentious, overplayed, distracting and/or just plain wrong -- ie if I showed up at lunch and heard ein klein nachtmusik, the Four Seasons, or Diana Krall, it might put me off my food.

Then again, I dont want some cutting edge, underground, just pirated in from a night club in Paris kind of vibe unless I am intoxicated or non monogamous.

Now I have NEVER tired of late night dinners at Cafe Luxembourg listening to Kind of Blue, but since my house is not off Amsterdam Avenue at 2AM, they might not quite fit either?!

So any help would be greatly, greatly appreciated.

1:00 PM, in the country, rack of lamb, Bloody Marys, and ______ on the stereo.

Thank you very much.

PS

And maybe an iTunes compilation run through the computer would simplify things as well?
