Because the Disney channel is THE teenybopper channel, so any crap that Disney can shove into their mouths gets eaten up. That's why shit like Jonas Brothers and Hannah Montana are so popular.

The lyrics to "Blue" are "I would bleed/I would die" or "If I would bleed I would die" IIRC. Amusing trivia: the local conservative talk radio uses that song as theme music for the "Blue Ball Open" Golf Tournament.
