See this example.
On the album jacket, the song by Arlene Harden is identified as “Lovin’ Man” while the record label just says "Lovin’ ".
I looked but could not find a specific guideline on which is the “official” title. Should I use the album jacket..or the record label?
Either way, I assume the “unofficial” title should be noted in the release annotation.
Also, I assume that we will document it as it appears on this specific release so that (if album jacket is considered “official”), the release title of the Marty Robbins song will be “White Sport Coat” while the actual title [“A White Sportcoat (and a Pink Carnation)”] will be noted by the release title’s relationship to its recording.
