Yeah, I wouldn't be surprised if my life trajectory went slightly differently if I discovered them back in 2002 as well.

Love Gunship, been a fan since their eponymous album (though no such track yet, haha) and I've been listening to Unicorn pretty regularly since its release.

I haven't heard of Your Inland Empire, but I like their sound from the track you linked. I'll have to check out more of them.

I don't listen to The Midnight a lot, but they are what immediately come to mind for retrowave with vocals.

Since we've only discussed artists with vocalists, I'm not going to go too deep into non-vocalist solo artists but I love darksynth, so I gotta give shout outs to Pertubator and Carpenter Brut who are the goats of the genre and have several tracks with featured vocalists. And a much more obscure darksynth artist without vocals I am going to recommend is Orax's Love Kills the Demon as it emotionally vibes closer to TBM than a lot of other things for me.

A bit more mainstream, Shiny Toy Guns has some similar energy to TBM, more so on their first and third albums, though I guess they've been on hiatus for 10+ years now.

Let me know if any of this tickle your fancy. I didn't pick out any real goth stuff, but I should have been asleep hours ago, ha
