I just uploaded a piano solo which is 40 minutes long, and I consider that as a complete 'song'. I felt in the moment when I made it, I found it naturally grew to that length so decided to stick with it until it ran it's course. So it wasn't a flex or anything :P
But regarding the length of tracks and the limits people have pushed within the boundaries of their musical achievments, It got me wondering... what's everyone's longest song they've ever made under these challenges, or other constraints? Of course I'm not saying the longer a song goes on for the better, because I'm sure many of my long piano pieces won't get listened to all the way through.
Seem to remember seeing an epic guitar piece uploaded early on in the challenge that was done during a skirmish that was quite long as I recall. I'd like to also hear of some past songs over the years that may be remembered as the ones that stand out.
And chances are mine are just a drop in the pan when it comes to the overall galaxy of the bulk song making challenges.... but I don't mind for I make it for myself as a sort of archive of my pursuits.
... so what's your 'record' record? :P
