Err... "Ein, Zwei, Drei, Vier...." ("The Student Prince")? Dire Straits are good. Floyd might be helpful if we associate drinks with apparent deep insights into life, the universe and everything!
All depends, back when I used to stay up later, and drink more, usually with whoever I was spending the night with, it was often Meat Loaf. Which is not an innuendo, it just happened to be right, and "Rock and Roll Dreams" seemed to get "whoever I was with" in a romantic frame of mind (though maybe it was partly my immense charisma

). Other times it was Celtic music. A matter of mood.
I don't often sit and drink, except if a friend or two calls on a Friday evening. One in particular is a muso so we sometimes stick on a bit of music. Nowadays it tends to be nostalgic stuff like Queen or the Beatles, whereupon my mates and I chuckle and swap tales about what we were doing back then. Though if the song is "Rock and Roll Dreams", I of course remain discretely silent!
Since (apart from some Friday evenings) I don't drink so much, I tend to associate special occasion drinks with any incidental music.
Last time music and drink mattered, I was in Kirkland, Wash. and my son and I decided to sit down and see if American beer really was like sex in a canoe. We went into the "Time Out" saloon, just because it seemed like a non-tourist bar, and had an Alaskan beer. The Stones were playing at the time. A guy with one of the few US accents I had trouble with asked what music I liked. I rattled off a few bands and he set up the sound system to work through a selection of Stones, U2 etc. A pity we didn't stay long enough for it to work. And there was nothing wrong with the beer.
On another day I was in a bar on Pioneer Sq., Seattle, waiting to start the Underground Tour. The bar had a nice late 1800s decor and the music was Johnny Cash. I don't often listen to him, but it seemed perfect.
