The longest song ever...

[DukeNukem]

Dopesmoker by Sleep

This stoner/doom metal epic clocks in at 1 hour and 3 minutes long,
so get your weed and your bong,
and listen to this incredible song!

I actually thought that "R-Kelly - Trapped in a closet" was the longest song, it seems I was wrong.
But seriously, I would check that out aswell if your a fan of R&B.

There's longer songs than that.

Jeff Wayne's War of the Worlds: 1 hour 30 minutes. Often split to seperate tracks but it's consistent enough to be one continious song.
Several of Dream Theater's songs are over an hour long.
Klaus Shzule released tracks that lasted from 1-2 hours.

Last but not least...
Bull of Heaven's "The Chosen Priest and Apostle of Infinite Space" was... 2 months long. It's mostly effects slowed down and general ambience, though.

Indeed. A lot of classical music is longer than an hour, as well. For example, Mahler's Third Symphony is around an hour and a half long, although I don't know if a symphony would be considered a song in the classical sense of the word.

I thought Jethro Tull's "Thick as a Brick" was the longest song in rock & roll.

I was just thinking the same thing! I have that on CD, and I have listened to it only once.
I much prefer a 9-or-so-minute-long version I used to hear on the radio.

How long is that Jethro Tull song? 20 minutes? Because Rush's 2112 is 20 minutes long.
