Right, this is getting hard, because I'm not that into music. Or at least, not songs. So here goes, 2 songs plucked randomly from my head:
1. Amazing Grace - nice words, nice tune, dead meaningful. This reminds me of when I were a lass at school, and went to Scripture Union, and sometimes the teachers would get us kids to chose the songs and introduce them, and basically every time we said "Now we're going to sing X, and... Just really think about the words".
2. At My Most Beautiful (REM) - this is my and Mr Smile's 'our song', not really for any romantic reasons, but we both liked it, so one day we were trying to decide what our song would be, and we went through some options and then went 'feck it, that REM one will do' and that was that. They do a nice version with sleigh bells.
