IDM stands for Intelligent Dance Music.... a bit of an overused genre name ....never been that popular in any country.
The trance I got in the 90s was called....IDM....
Recent for me:
The Devil Wares Prada 7/10
Deathproof 5/10
Planet Terror 7/10
A Nightmare Before Christmas 10/10 classic!
Silent Hill 6/10
I am Legend 7/10
ambient is boring to me generally, however a few people are able to make non-boring ambient like Richard James
I don't shop for ambient though, too much sucks IMHO.
do you want me to describe it, haha
it is on a lot of synthesizer ROMs - at least I know Yamaha, Roland, and Korg
i.e. anyone could just buy a cheep 90s synth and get this sound
+1 to Aeros comments
Repeditivness comes from not thinking the track through enough. Take a break from it and listen to your favorite music or go for a hike.
Or you can come on over here and listen to what I'm playing with ATM.
Sometimes I shelve something for months and then come back to it when I'm fresh.
Listening to what you've done over and over can drain the creativity.
