Nice list, Mortte! You're definitely spot on about Flying Saucer Attack. I don't think Instrumentals 2015 will make my final top ten personally, but it was definitely a great album.
The early stuff is quite a bit different. More of an ambient/shoegaze vibe. I hope you get around to digging into it at some point, because it's really good stuff. Underrated in the grand scheme of things, but just as significant as a lot of the stuff that received more attention (MBV, Galaxie 500).
And I agree about Cave and Ellis. They are top tier score writers, up there with Reznor and Ross.
Sadly I didn't listen to the new JSBX enough this year for it to leave a lasting impression. I should get back to that one.
