So I decided to sort out my projects based on what album I want to put them on (each one follows a particular narrative about events that took place in the past) and on the year that they were started in. After I deleted all the junk that I couldn't do anything with, I wound up with 199 unfinished songs. Those are all the songs I've ever written (except for the files that I lost or intentionally deleted) and none of them are even 50% complete.
The crazy thing is that I gathered 105 songs in one folder, for one album, because they are part of the same narrative. This is when I came up with the idea for this thread. I like long songs—the longer the better—and I intend to never write anything shorter than 4 minutes because I think that I'm wasting a song idea if I make it shorter than that. This means that this 105 track album will be more than 7 hours long. It will take me a few years to finish and it won't be the first thing that I will release but it is a crazy long album and I don't intend to reduce the number of tracks or length in any way. I wouldn't really know what to do with the songs otherwise.
As for preferred length for releases, I must say that I like albums the most, but I guess EPs are fine too. Anything shorter than that seems like a waste of time or just not long enough to tell a compelling story. So I generally want to release stuff that's at least 6 or 8-tracks long and there's no upper limit as you might have gathered from the previous paragraphs.
So what's your preferred length for individual songs and releases (EPs, albums, etc)?
