I should've checked the forums earlier, gosh! It's nice to see that someone else is going just as mental as me off of these. More, even, from what you've described :3 Getting stuck in your head is one of the things the files are REALLY good at, which it sounds like you're experiencing firsthand. Eventually all those babbled phrases and jingling tunes that are rattling around in your head start stealing away your focus from the stuff that you're doing. It's a little surreal how babyish things can start to feel when you forget how to tie a shoe because you get lost in those thoughts, or find yourself bouncing in your seat humming "wheels on the bus" in the middle of eating your dinner.
For what it's worth, it's been my experience that if you just stop listening for a while, the effects will gradually dull back down and go away. A couple weeks off usually clears things up pretty well for me. Try to keep that in mind (if you can), should you feel like you've gone a bit too deep. Nothing wrong with pulling the ripcord! Especially if real life has stuff that needs taken care of. Besides, that frenetic, simple-minded behavior all comes back fairly quick once you start back up again.
The only thing that's really stuck around for me after taking a break for roughly a month this last go-around is that when I have some time to myself where nothing else is going on and I don't have any other responsibilities, my mind just kinda...I suppose 'relaxes' is the right word. Melts, maybe? Stops bothering to think too hard or pay much attention to anything. Thumb or binky goes into mouth, sometimes a hand goes to down to pat my diaper (crinkles!), and I just kinda sit there in a happy hazy bliss for a while. It's so comfy!
Fuzzing out like that while doing little stuff in particular is just heaven. Almost like a mental switch or trigger that drops me straight down into littlespace, which is something I've historically struggled with. And it doesn't feel forced! It's more like something I consciously 'let' myself do when I find myself feeling safe and bored, though admittedly I haven't felt the need to actually try stopping it so far, so I could be wrong about how voluntary it is >.>
Anyways, sorry if it's weird to hear this kinda stuff from the file maker. I mostly make these for myself when I get frustrated that I can't find the kind of files I like to wooze out to during baby brain time. I'm actually working on a new one right now! Learning a new DAW (Reaper) has been rough, but I'm liking what I've got so far. Tracks and music are laid out, just gotta lace in some distractions and figure out if I wanna use any sound effects this go-around. No promises on a timeline, but I'm hoping in a couple weeks or so.
Oh, and if anyone wants to grab an old version of a file, you can always find anything I release on my Mega archive:
