This set from Freaky Loops is pretty cool if you are scoring film trailers. I can see listening to the tracks how most of them would fit perfectly in the synch world. I don't really see the fit for use in standard music though. Whether it's action or horror- these will fit great. A bunch might work as intros or can be used if cut up to work with a particular beat. All that being said- if you need effects for trailers and film beds, this is will work really well.
