Im not so much into music though, but I do like Presley. Amongst my favourites are "it's now or never" and "can't help falling in love with you" I'm not sure I've heard too much of Zeppelin's songs though..

BTW @icedrum, have you listened to "it's now or never"? You'd love it. Especially if you have someone close you love but they aren't sure they wanna settle with you. I did.
