May I remind that this thread is NOT about the new soundpacks, neither was the OP's question about soundpacks.
Anyways, if you want to find some soundpacks to download, go to:

BlackStar, soundpacks are part of the new way in which Messenger Plus! can send sounds to other Messenger Plus! users. Multiple sounds can be exported together into .PLP files. These soundpack files can be send to your friends or downloaded or whatever. They should be imported back into Messenger Plus!'s Soundlibrary if you want to use the sounds within them.
