Your point being? JG was talking about the difference between MIDI files, module files (including .mod/.xm/.it/.s3m) and stream files (including .wav/.mp3/.ogg). Wave and MP3 files are similar in that they encode the entire audio stream in some way, while module files contain a bunch of short sound snippets and the instructions on how to play them.

You're also wrong, in that wave's do not necessarily use a lossless encoding. MP3 is a mpeg container format, generally containing audio compressed with mpeg-2 layer 3, while wave is a riff container format containing audio in many possible formats (uncompressed PCM, ADPCM, u-law, a-law, ogg, mp3, ac3 or whatever you want). Almost all wave formats are lossy, however waves usually use uncompressed PCM.
