	~~Music is stored in Lego Island SI files~~. SI ~~files are derivatives of the {{Wikipedia\|Resource Interchange File Format}} best known as the basis of AVI and WAV files.~~

	~~All music appears to be 11025Hz Mono Signed 16-bit. All bytes are little endian.~~

	Music appears to begin with a <code>MxDa</code> and is split into chunks of <code>MxCh</code>. The <code>MxDa</code> header contains information about the PCM audio in the <code>MxCh</code> chunks. The first <code>MxCh</code> appears to be information about the remainder of the chunks in the <code>MxDa</code> structure.
