I haven't heard Jungle being referred to as IDM before, but it's quite possible ;) Personally, when I think of IDM I always think of Aphex Twin, Squarepusher etc. Some tracks by Venetian snares (IDM/Breakcore?) used the amen break in a similar fashion though, just faster and way more glitchy. I think the stuff LTJ Bukem produced usually was referred to as "intelligent DnB".
Anyway, thanks for the thumbs up :]
