That's a very tough question to answer because it's asking about specific artists. A lot will depend on my mood. The HD650 is tamer and more romantic. In this sense it may remove some aggression from the music. If that aggression is what makes the music an emotional experience for you then I would say the HE500. What the HD650 will do though is it will give the music a sense of depth, bottom and a lush quality that can stir the emotions in other ways. The HE500 will yield more detail and will feel quicker by comparison. If you experience emotion from detail and speed, then the HE500.... I hope this helps.
Depending on my mood, I would choose one over the other for these artists. I think personally, I may reach for the HD650 more often because I personally like the added lush quality it gives aggressive rock music.
