Thanks a ton for all these sounds. There was a problem extracting a lot of them though (642 files to be exact). WinRAR reports "Unknown method" and 7-Zip reports "Unsupported compression method".

EDIT: Apparently, 642 files is not only the total number of files that had problems extracting, but it was the total number of files in the archive. What did you use to compress this archive?

EDIT #2: Forgive my ignorance. Apparently my copy of 7-Zip was a bit outdated (a little while before LZMA2 compression was supported). I updated 7-Zip and all is well now. Thanks!!
