What is the longest song you know?

Haha. I thought I have stumbled upon what would be the longest song in the world. Now, it seems I am wrong. However, I don't believe this very long song (999 years in the making) will ever become great or phenomenal. It will only be a lame song. How will the initiator of this idea live to see the completion of his work? That's just nonsense. But I think there are only a few long songs that really make sense. One of them may be Bon Jovi's Dry County, which I happened to come across lately.

That one clocks in at 9 minutes and 57 seconds.

Yeah! What's the point of it being the longest song when people don't like hearing it? Most "real" songs by "real & popular" groups weigh in at around the half hour mark. Pink Floyd & others come to mind. I think it all started in the 1970's to try & record longer than other bands. They figured if it was long & good & told an interesting story that people could relate to, it'd get played on radio more often (making more $$) because the DJ wouldn't need to shuffle through so many different records all the time. Just play American Pie or the Bee Gees & that oughta do it for a good eight or so minutes!
