Recommedations for a Cocktail Party

I've always envisioned a cocktail party and jazz going hand in hand. However, any old jazz won't do. It's my opinion that the jazz that's played needs to set the tone of the party. It should be upbeat - yet not over stimulate so as to detract from a conversation. It should be like something that's on a slow cook - simmering just enough to get things going, but not enough to burn. I believe the selections below meet that criteria (note that currently the sample links are bad. I need to get the kinks worked out. I apologize for the inconvenience):
