Coming back to yesterday's track, it just didn't strike me as being on par with the rest of the music on the album. I think this is because, while all the other tracks proceeded in an organic fashion with no clear plan, this newest track proceeded more superficially with a clear goal. As a result, it comes across as a pale imitation rather than an original.
So, instead of beating it to death, I spent the morning doing final tweaks on the 6 completed tracks. Here is the album as it stands this evening:
To my ears, it feels very complete and cohesive.
Still, we do have a few more days left to experiment, so I'll ask one last time for your suggestions: sounds? ideas? emotions? images?
Who knows? Maybe I'll stumble upon some hidden gem tomorrow morning!
