I have noticed that in the recent trailers, the music seems to change every few seconds. Personally, I prefer the old way, where the same song played throughout the entire trailer, rather than the constantly changing music, which is quite distracting.
Of course, it's just a trailer, so it's not that big a deal, but I was just wondering what the reason for the change was, and if anybody else agrees with me that the constantly changing music is rather annoying?
