The Lyricist/ Illusionist?

All of us have our favourite songs seemingly tailor written for each specific mood or occasion that they bring to mind whenever we hear them. If we need cheering up we may listen to "Put On A Happy Face" and while that example is admittedly pat, we all identify at some time or another with a certain song which for us will always represent a certain something: a lost love, a wedding, a divorce, a child's teen years (we still hate those songs!!) and of course certain songs will always remind us of parents no longer here but in truth it is invariably the lyric that sucks us in. The music may be less than stellar but if the words fit the bill and provide what we need, that's good enough, in fact it's more than that, it's PERFECT! Thanks to the lyrics, we take ownership of the songs we've chosen. (ie.."that's OUR song") Which brings me to my question; how is it that a lyricist can march right into our hearts without so much as a 'by your leave' and make that unseen connection with us when we are the only ones who take the lyrics seriously? The "lyricist" is doing a "job" writing words to sell. He/She does not necessarily feel the way the words tell us he/she feels, in fact I wager that the true lyricist could actually be a mercenary disguised as a romantic who is totally adept at his/her craft. We are lucky that we never get to know the lyricists of those songs that have become 'our' songs because if we did, perhaps the sense of disillusionment would be too much to bear and we'd never find the perfect lyrics to deal with that.
