‘I’ve always had an obsession with memorizing complicated lyrically intricate and fast songs,” he told Jimmy Fallon on the Tonight Show Tuesday night.
“It’s a disease.”

Warning: Radcliffe delivers every single word (and maintains a pretty good American accent while doing it).
Horns opens in theaters on Friday.
Watch Daniel Radcliffe rap, above.
