I'm one of those people who has some reason to relate to almost every single song they hear...even if it's just one line or something. Well...hopefully there are other people out there like that, haha.
I'll try to post all of mine without rambling or explaining them tooooo much. xP
To some degree I guess I've been able to relate to Pretty Baby, haha. The same probably goes for Unsung and Twilight. While I do like BNN, I haven't really had the same sort of connection with it as I have the with other two (and the upcoming) albums.
From Harmonium, the first one that comes to mind where actually being able to relate to a song is concerned is Afterglow. I love Afterglow so much, haha...when I first heard it I knew I liked it, but I never really had much of a reason to connect with it until last summer (2010).
For a very short while I could relate to parts of White Houses, but just a few lines. To some degree, I'm guilty of taking things out of context and applying them to my own life. Specifically "I'm so excited, I haven't spoken". I guess I kind of did that to the other part, too...that being the whole part about having friends you're really close to and then leaving them in a sort of bittersweet way. Sorry if I'm not making sense now. :x
Anyway...I can somewhat relate to Who's to Say and Private Radio, as well as a few specific lines of Annie.
From H&T, I'd say I've been capable of forming some connection with every song...perhaps not the entire song, but certainly lines. Even Nolita Fairytale. I'm sure few people can really FULLY relate to that song, but I think it's not too far fetched to relate to it because you've (at least temporarily) found a perfectly blissful environment/lifestyle for whatever reason...but maybe it's just me. XD
Anyway, the main ones I relate to (or have at some time been able to relate to) from H&T are Spring Street, Come Undone, The One, Heroes & Thieves, Home, and More Than This...that's a pretty big list...aaaack.
From her demo tape, I've actually been able to relate to Last Fall and Wonder for different reasons.
Sorry for rambling on and on and probably not making any sense at times. xP
