Yeah metallica's intros usually get my attention although some are rather long.

...and yeah I keep going back to Rush but the fact is they're ****hot with intros....at least I think so. Check out Spirit of the Radio......first song of theirs I heard and I was like 'woa these guys can play!' Its really cool when that happens coz many times i've downloaded or bought my first taste of a band I've wondered what everyone was yelling about when I heard my first intro.

Another great intro is The Song Remains the Same (Zeppelin) Although lengthy there isnt a not wasted......I guess I like economy in music.
