My thoughts (potential spoilers for ep 2, mentioning details in teaser shared last week)
This gives me some pretty ethereal vibes, dare I say perhaps even void-y. But I think this will actually play around the time we see Pomni getting thrown into abstraction basement (0:30 in the teaser).
This preview was actually shared a few days before the teaser came out. When the teaser dropped, Evan's tweeted (nitter) was "I can't believe someone hypnotized Pomni and then stole her body" with a screenshot of that clip, which I feel reinforces my theory (also get out reference). Those were Evan's only recent tweets, nothing else in the middle or since.
So what will be going on here? I think this is Pomni's psychotic break before she starts abstracting (note her right arm is already gone as she's being lowered in). Those staticy interruptions towards the end of the song clip will probably be flashbacks to things she saw/experienced while getting Space Odyssey'ed in the pilot.
Then, she starts abstracting and Caine gives her the WR for Any%'ing the Digital Circus.
Then, she wakes up.
This is starting to be more thoughts on the teaser as a whole rather than just the song, but I think the abstraction is just a nightmare at the start of the episode (possibly even a cold open?), then she's startled out of bed and clips into the block and the real fun begins.
Who knows? Maybe the characters here will be totally disposable. But I think it'll be a lot harder to make any sort of proper story progression like that, and given the significance of Pomni herself (see my thoughts in the Pilot discussion), I highly doubt she's going to be the next one out already.
But hey, that's just a theory. What do the rest of you think?
