What's the LONGEST song of your favourite artist?

Nightwish's The Poet and the Pendulum is 13 minutes and 54 seconds long (and yes, it is a reference to Edgar Allan Poe's The Pit and the Pendulum). However, Song of Myself is a very close second at 13 minutes and 37 seconds (and yes, that is also a reference to Walt Whitman's Song of Myself).

Although they have a half hour long live version of Dazed & Confused, Zep's longest studio recording is In My Time Of Dying, coming in at a little over 11 minutes long.

And it's a pretty fantastic song, if I do say so myself.

"Future" by Paramore is an eight-minute rock-out session, with excellent reflective lyrics and rare lo-fi quality in the beginning.
