Osmosis for learning tunes is fine and the best way but have you never tried to write words from a recording and not been able to hear them, or rather you hear SOMETHING TOTALLY DIFFERENT and the more you hear them the more you hear the wrong words, when I was a child I thought the angels in the carol were very happy when they sang "ha ha" - you know, "ha the herald angels sing"?! I was recently trying to learn a song and had no less than three different recordings, still couldn't work it out but thanks to you kind people out there I was put out of my misery...
