I'm with you there. Led Zeppelin is my favorite band of all time. And classic rock is the best music of all time. Now if only I could write the best code of all time while listening....

silence anyone?

I've been known to listen to Zep and other classic rock, it's about half of what I listen to, but usually not while programming.

I'll second the zeppelin. Although generally for me its Detroit Techno, it has a lot more in common with led zeppelin than you probably think. Also I listen to a lot of motown as well.
