I'm not big on long-distance dedications, but a few weeks ago on KEXP, the DJ played a song requested by a man whose girlfriend was going through chemotherapy or surgery. (My memory is a little fuzzy. It was early in the morning.) It was "Destiny," from Zero 7's 2001 album Simple Things. I've heard the song plenty of times, but only in that moment did I realize what an apt relationship tune it is, expressing how each partner picks the other one up during hard times.
Anyway, I've now been listening to the track, and Simple Things, quite a bit in recent days. I hope that couple are doing OK.
