Longest Songs Youve Ever Heard

make a normal song, stretch and slow it down in a daw, export it, boom.
the formula to every bull of heaven album

wow what kind of DRUGS were they on when they made this?

Stairway to Heaven and Bohemian Rhapsody? Seriously? That's either a bait, or you don't really explore music. Pink Floyd's Echoes-20 minutes, Atom Heart Mother-23 minutes, Iron Butterfly-In a gadda da vida-17 minutes, the list goes on, long songs isn't this much of a big deal, it's not special.

Supper's Ready and Sister Ray are longest songs i ever heard

Yup.

can anyone beat 1 hour 20 minutes?

progressive music in general has a lot of long songs. This prog metal band for example has a 22 minute song and it's fantastic.

Cassandra Gemini by mars volta was over 30 minutes but I've seen it referred to as parts. I don't know if it was split up into multiple tracks but the copy I have is one track.

Haven't listen to the whole album because it's like 9-10 hours long
