My favorite is this one.
Hijo De La Luna The story depicted in it is a translation of the song itself but the main thing I like about it is that its serious. Yes, seeing every body dancing around to a random pop song is funny but after about the hundredth time they really start to look the same to me. I realize that a lot of people probably want to try their hand at it and there is nothing wrong with that but when EVERYONE does the SAME thing with no variety... Its like anything else, it becomes so popular it becomes overused. And while I /don't/ want to say that the more "dance-themed" videos have less effort put into them as there are a few that have some very creative ideas worked into them that would probably be very hard to replicate. However, there is also a large number of them that don't. Most people can take fraps (or some other screen recording software), click "headbang," throw in some music and call it a Feral Heart dance video. If thats what you like, more power to you, but the majority of them do look very much the same to me, just with different music.
Seeing a more serious tune for a FH video is a nice change of scenery.
