Question:

Does CLM support MP3 as a type of Media? CLM supported media file formats are listed on the Supporting Custom CLM Content page but it does not indicate MP3. 

Answer:

CLM supports MP3 as a type of Media through the use of HTML5.  MP3 files can be successfully played as part of HTML5 content.  It does not package the MP3 file as a separate zip file just like the approach with MP4 files.
