I might get some crap for this, but ever since I was little this has always felt like the quintessential "night" album for me....
I think the reason is because when I was about 8 I was taking a road trip with my family and my dad put this on. It was a late drive and I was half asleep while listening to it, so it got burnt into my mind in that context.
So, yeah, I guess this also counts as a guilty pleasure. So I like some Harry Connick Jr. Whatever. These days, though, I usually tend to listen to some chill electronic like Air or Boards of Canada...maybe some Sigur Ros.
