oddly enough, i've actually had discussions about this quite recently more a few times, & i've decided i would like "in my time of need" by ryan adams played - which is a country-tinged song by one of alt. country's (& music in general's) greatest artists. it's a somber, but quite beautiful, song about staying with someone through hard times & until death, & since i doubt anyone here really listens to ryan adams, i'm going to go ahead & post an excerpt:

cause it ain't like it was back in those days
when everyone would offer up a hand
these old bones are worn, i've grown tired some
& i know my time is surely gonna come

lord, we married young & stayed where we came from
& gave those children everything we had
will you stay with me in my time of need
though it seems we had such little time for us

will you say to me "a little rain's gonna come"
when the sky can't offer none to me
cause i will come for you when my days are through
& i'll let your smile just off & carry me
