3. Killswitch Engage – “Holy Diver” (Dio)

Another tenet that makes a cover work is reintroducing it to a new generation which is exactly what Killswitch did. There are probably tons of youngsters out there who have no idea that it is not an original. I love that fact the KsE never did a cover before this, but when decided to, they knocked way out of the park. Plus, they wrote much better guitar solos than the original. Love it.
