I think that both artists did a good job on "Turn The Page". The heavy style from Metallica fits quite well to this song. But I like the calm-country-style version by Bob Seger better.
So what is your opinion? I can imagine that lots of younger people don't even know the original version by Bob Seger. So take the chance and listen to this great song.
