There is a problem with saying that some headphones aren't good with fast-tempo music in general, because even a single guitar or classical music can be extremely quickly paced, but well-represented on ultra-warm headphones like the HD650.
I tend to distinguish my genre distinctions when it comes to equipment by choosing to point out the extent of the layering in the music. When most people claim that a certain headphone (like the TMA-1 or HD600) don't go well with elecronic music or heavy rock, it's usually because the sound turns to mush due to the over-warm sound signature of those headphones. It doesn't necessarily have anything to do with the literal speed of the music, but by all the layers of production present.
A super-warm headphone won't do very well with Infected Mushroom, but goes great with Moby. They're both electronic musicians, but the former's music has much more going on in it than the latter. Such a headphone won't do well with Suicide Machines, but will love La Dispute. Again, the latter has a more stripped-down sound than the former. We tend to mention genres instead of layering because it's easy to generalize. We tend to think that electronica and metal are always super-loud and full of layers.
