Daniel Radcliffe Raps Blackalicious' "Alphabet Aerobics"

I caught this the night it showed on The Tonight show, but it came up again today.

Could the threatened innocent boy wizard seem any different in a beard throwing out rap?

Does it seem like real rap coming from a white, English boy? I actually find it less annoying

to the ear than most rap, but I cannot explain why.  Inter-generational resistance to change

is how I used to explain it but now I'm lost for why.
