I've watched a lot of PMVs and HMVs and I gotta say yours, especially the second one, are among the best when it comes to the way how the video goes well with the music and vice versa.

So I'm curious: How do you choose the music for your vids? Do you just know a lot of EDM and feel some of them would go well with a guro PMV? Or is there another way to choose them?
