Consonant Works CDs consist of two sessions; the first session is CD-Audio with CD-Text, the second session is CD-ROM.

The CD-Audio session will play in all CD players. Embedded in the CD-Audio session is CD-Text information such as the CD’s title, performer, composer and track information. CD players that display CD-Text information are rare; however some computer media players and many new car players offer CD-Text support.

The CD-ROM session, ignored by CD players, is recognized by most personal computers. Many Microsoft Windows® operating systems will auto-run the CD-ROM session, and attempt to execute ShellRun.exe, offering user selectable options. If asked, ShellRun.exe is safe to run.

Example of the option pop-up screen from the Christmas 2015 CD created for Digi-Key Electronics:

Shell Run

Windows® Media Player, and several other media players, properly interprets the command issued by ‘Play CD Now!’ but WinAmp® does not.

Windows-10 has substituted “Groove Music” as the default player for M3U files (the playlist format for MP3 files) and but fails to correctly process a M3U playlist! This shortcoming has not been corrected as of Windows-10 release 1511 of mid November 2015, although the problem has been reported by many to Microsoft. You may avoid this by changing the default for the M3U file extension from Groove Music to Windows Media Player. The procedure is “Start>Settings>System>Default apps>Choose default apps by file type”, which is found at the bottom of the page. After selecting that option, scroll down to .M3U and change the default from Groove Music to Windows Media Player. The Christmas 2015 CD created for Digi-Key Electronics uses ASX playlists, which default to Windows Media Player, thus avoiding this problem.

If the menu does not appear; view the files in the CD-ROM session and manually execute ShellRun.exe or open the files with extensions asx, mp3, m3u, and pdf manually.
