Most of the time I prefer pure instrumental. It can be either electronic or classical music. These are usually movie and game soundtracks, though I do listen to Wagner, Stravinsky, Kraftwerk etc. On some other occasions I also listen to blues and some forms of rock, like hard rock (Black Sabbath), and more specifically heavy metal, which is a form of hard rock (Judas Priest, Iron Maiden).
In an LBT video I would prefer to use some instrumental, like on a piano or even a synth, to try to convey the emotion shown by the video. It would be probably be a melancholic video if I were to make one.
But your videos are good too. You are good at editing and know most of LBT by heart, so you can always find the perfect scene for some part of a song. As I said, "Be Yourself" is a video I greatly admire, more than some TV episodes of LBT.
