Thanks again, @ChunYinZi ... I'm amazed at the wealth of knowledge represented by the people who post here (and a little intimidated by the fact that there's so much to research!).
I'm also a little dismayed to realize that, at this point, a lot of the material that I can't identify myself is likely to originate with discontinued releases, as these two apparently are. The methods that @Craig-UK have provided me for my own research have been tremendously helpful -- but apparently they meet their limits when an album has been out of circulation for a decade or two.
For the two that you have identified already -- I wouldn't have known where to begin. Amazing work.
For 144, I agree, it's very possibly FirstCom -- a lot of their late '80s/early '90s tracks were in wide circulation in national and local TV commercials; it seems like they were one of the "go-to" companies, and I know that this track was used in quite a bit of promo work. I'm not as familiar with Sound Ideas, but their albums may have had the same status.
For 170, I wish I had a longer clip, any clip. I've heard the track at greater length, but it's the same spooky/suspenseful bed throughout. The source material was specifically from 2008; I'd be surprised if it was from a '90s album.
Thank you again!
