Most rockers record covers album as a fun way to relax while still getting a record out of the way. Its different for Joan Jett (a solid tunesmith in her own right) since covers have always been a major part of almost all of her LPs. Here, Jett picks tracks that seem to have influenced her own sound -- from the Chamber Bros.' "Time Has Come Today," to Nazareth's proto-power ballad "Love Hurts."
