This is an oldie by Billy Joel but its a great song:

"And the waitress is practicing politics
As the businessmen slowly get stoned
Yes, they're sharing a drink they call loneliness
But it's better than drinkin' alone"

- Piano Man (Billy Joel)

Here is a great Irish song, if you like Irish music, you need to hear this one:

"You'll have to excuse me, i'm not at my best
I've been gone for a month, i've been drunk since i left
and these so called vacations will soon be my death
i'm so sick from the drink, I need home for a rest"

-Home for a rest (Spirit of the West)
