Love, Insulation, and Speaking to be Heard

I read about a Swedish band; they sing their songs in English because it insultates them from lyrics that would be too raw, too painful to sing otherwise.  It made me think of birthday cards, of poems written by machines, of leaving notes for loved ones instead of saying the words ourselves.

Is it just human to behave this way? To only say what we feel when there is a lesser chance that we will hear our own words?

Does this makes its way into our worship? Or is it rather, quite the other way around? Is our ability to show ourselves, and to even know ourselves, tied up in our love for God? Are we unable to speak truly of ourselves because we unwilling to speak truly of Him?

What do you say?
