I was looking up the lyrics to Kenny Rogers "The Gambler" as I assumed it was not only the best song written about poker, but really the only half-way decent song written about poker.
Turns out it's terrible. Musically, there's nothing going on. That "know when to hold 'em" part that you can sing? Yeah, that's the tune for the entire song.
Also, it's a really depressing song about poker. The verse that follows the first chorus is:
Now ev'ry gambler knows that / the secret to survivin'
Is knowin' what to throw away / and knowing what to keep.
cause ev'ry hand's a winner / and ev'ry hands a loser,
And the best that you can hope for / is to die in your sleep.
Guess what happens to the Gambler after he drawls that at us? He dies in his sleep.
