I can't say that I'm loving the trailer for "Horrible Bosses" but I will say that it use of music is almost perfect. Guy Ritchie helped make Black Strobe's "I'm a Man" a trailer staple (he used it in Rock'n'Rolla) and "Can't Stop" by the Red Hot Chili Peppers has one of the best opening riffs in recent memory. I think those two songs could make any trailer better. I think even the crappy Bridesmaids trailer could have been salvaged by these two songs. I think might go up there with NIN's "The Mark Has Been Made" (used most effectively in "Man on Fire") and Clint Mansell's Lux Aeterna (which was originally in Requiem for a Dream, then in Lord of the Rings, and countless trailers after that) as the best trailer songs of the early 21st Century.
