No lyrics (samples OK), somewhat "haunting" melody (even if trite in some respects), but a defined melody and song structure (at least as defined as it might be for electronic music), and definitely minor key. If it helps, think of sad cloudy day songs. Another similar song is "Bad Stone"
on the Vegas album by Crystal Method.
Boards of Canada, most Cocteau Twins, Gorillaz, Portishead, Bon Iver, Mikkel Metal, Album Leaf, M83 are all out. Not quite what I want, too major key, too upbeat or too weird, and I already have them anyways.
Basically, I just want more of "Hotel Intro." Except the rest of Hotel has words and sucks, and I already have the "Hotel Ambient" album (which is too much of a go-to-sleep-now kind of album). Pandora fails me.
It seems similar questions have been asked a lot, but they are all for "upbeat" songs. Gross! Many thanks for your suggestions.
