An original song from Jacob to Bella about how he would be the best choice for her instead of Edward. It is meant to be sung Von a guy (Taylor would be amazing)so just imagine it as Jacob's voice :)
Here's a clip from Twilight Lexicon. They interviewed Taylor who is JUST adorable as Twilight Jacob. The interview starts at 2:18 but do watch the whole clips! It's interesting!!
WARNING: Shows some scenes being filmed so do not watch if Du don't want movie spoilers. Some pretty good Kommentare from Robert Pattinson, Kristen Stewart and Nikki Reed.
