if you listen back to some of the early beatle songs you can hear the finger squeak. i think that it gives the song identity, and even more it's cool, yes you could get flat wound strings and you would have a flat wound sound, instead of the bright sound of the acoustic string, cause that is what acoustic music is all about, maybe you should learn to play the guitar, then you would understand for yourself. the breating part i can't comment on cause i don't sing very much.
