what is the longest song ever (in minutes)?

its john conltrane with 150 minutes, it was an live performans

I vote for that Mars Volta song that ended the last record ... even though I think it lasts a little more than a half hour, it loses nothing in the way of intensity or tempo until the requisite relaxed warble segment about 20 minutes into it. because of that, the thing feels like it goes on for about 90 minutes.

It annoys me when people refer to instrumental compositions as songs. Songs have singing.

Iron Butterfly's - In-A-Gadda-Da-Vidda!
Damn this song is long....

I hardly think that opinion is limited to Geir. Beethoven's piano sonatas are not songs. Schumann's Liederkreis are songs. It seems like a pretty easy distinction.

K I just thought this would be fun. My songs I know arent as long as the ones you know and I dont really know those songs. but I have a couple that are around 9 minutes long
Bon Jovi-November Rain
Phil Collins&Genisis "Tonight, tonight, tonight"
Don Mclean- American pie
Those are 3 very good songs!
Everythigns else I have is 7.3 and less.
Ok so I have a few more
Fleetwood mac-17.18-"The Madge Sessions"
Jimmy Eat World-16.11-Goodbye Sky Harbor
Prince-25.59-The war
Alright so thats just from me. Thanks People.

Actually I think it's Michael Jatas with "Love Is Hurting Me", it's like fifteen minutes! You can check it out by going to putfile.com and typing in football and looking for the one sayin greatest.
