A catch-all term for electronic music utilizing more than a typical 4/4 beat and a tired, rehashed melody looped for 7 minutes.
As far as I know, this is the most uncommon EDM-genre and you'll never hear it in a club. It's pretty hard to dance to, that's why it's also called "bedroom music" or "artcore".
If you sincerilly LOVE most styles of obscure music, you'll LOVE IDM!
But now it can also be use in gaming and/or several chat place to replace the words to " I don't mind" or "It doesn't matter"
Whatever the word you see fit is your choice.
Tim: sure, idm.
