Food and music ideas for a 'grown ups' party

[strawberry]

We're having a party and I'm beginning to panic!! Haven't had a house party for ages.
I need ideas for food and music please.
I don't really want to do food but feel the need to do something more than crisps - what would you expect if invited to a party and any ideas for food?

Most people coming are in their thirties and forties so the music will probably be mainly 80s. Dh and I like Brit pop and rock music but perhaps not that great for dancing. What would get you dancing? (Apart from copious amounts of alcohol)
TIA

anti pasta
cold sliced meats
breadsticks

Designate a bartender and have loads of diffrent cocktails

Lots of champagne

When is your party?
Martha Stewart does some great party books (amazon)

Thanks PPB.
Thought I'd do some pitchers for cocktails. Anti pasta a good idea and I'll check out Martha Stewart.

In the summer sales I bet you could find all sorts of plastic cocktail glasses
