That file is not audio file, this is what file reported:
onemoretime-onemorechance.wv: PE32 executable (console) Intel 80386,
for MS Windows, UPX compressed
Inspecting data in hex editor is looks like exectuable stuff was put
at begining of wv data.
If this is not some kind of trojan/virus than its probably feature
that allows to auto decompress
wv files on sytems without wavpack decoder.
