there's multiple title songs
I think Ecafymtoohs is talking about "Hydraulics" & "Other".
Frankly, both start a bit too energetic as opposed to "DEEP" which is pretty self contained in comparison and introduces a much slower start and a ton of anticipation.
Personally, I hate all 3 equally :D
I actually like the new unlisted track that you've added which I mistook with "It's Chilly in Here" at first.
But again, pretty sure that's unfamiliarity biased. I can't recall the last time I played a game and didn't nag about the title ost not belonging to the title screen.
