Ishkur's Guide to Electronic Music

Some might already know it, some won't. Here is THE guide to electronic music.
It contains around 180 genres and 1189 samples.

"If you hate the guide, then you obviously didn't take it with a pound of salt like you were supposed to. Go take your anal-retentive sense of humour elsewhere."

Now let's make a little game out of this.
Who can tell me in which genre(s) the artist belongs?

LTJ Bukem
