I agree it's about people with uncommon abilities but 1. I think she says "We go undercover, wait out the sun," which is willingly being undercover, not forced, so the situation is positive. 2. I took the "but I can't be one of them" line as not wanting to be an everyday person and happy to be exceptional, so also positive. 3. "Where the streets are empty that's where we run." I don't understand this line. Doesn't seem to fit to me. 4. "We could be heroes" seems like an unfortunate waste of talents, so doesn't fit with my positive interpretation, but it seems like it's sung as because of the apathy of everyday people, not because they're forced by something else. 5. "You and me we've got the world in our hands." That's about as positive as it gets. Don't want to be everyday people who don't understand and spin around and round for hours.
