Considering the post I made a few minutes ago --- this one is tough for other reasons. I almost said to Hubs that if he keeps up with his attitude and negativity that he and I will never get married.
During days/weeks where he hasn't irked me, this one would STILL be really tough for me... because Hubs and I don't really share the same musical taste (and we are common-law).
Hubs has previously said that the song Someday by Rob Thomas makes him think of me/us:
Maybe Beloved (the acoustic version) by Ben Harper...
Or "Greatest Day" by Take that... http://www.youtube.com/watch?v=zHzMLGH1Rfs
With Husband v1.0 we had the song Beautiful Freak by the Eels as our first dance at our wedding in May 2001:
day 24 - a song that you want to play at your funeral
day 25 - a song that makes you laugh
day 26 - a song that you can play on an instrument
day 27 - a song that you wish you could play
day 28 - a song that makes you feel guilty
day 29 - a song from your childhood
day 30 - your favorite song at this time last year
