Where did you get the album?  Was it a rip of a CD or was it a download?

 Do you use tagging software?  If so check the tags to make sure they are correct.  Make sure the Track Number tags are 01, 02, 03… etc.

Thank you for the helpful  reply.

I purchased the  album from iTunes Store.  It is stored on my Mac Mini and displays the songs in order in album view and in the finder. The album has 12 tracks, songs 01 and 07 are listed in Sonos after track 12. I do not have tagging software any suggestions for a Mac system?

 I believe MP3 Tag is available for Mac.

Thank you
