I like to keep track of the exact origin of a rip because I often have several editions of a song, on one or more CDs, one or more vinyl albums, even one or more 45s. Right now I put the label name and Ccatalog Number in parentheses following the album title, but this can confuse cover art lookup.
Can anyone recommend the best field to use for this, a field that isn't also important for something else? Or does this require using a custom field?
If a custom field is required, that is simple but maybe surprising, because any commercial recording, CD, DVD, whatever, has a Catalog Number, these days usually printed with a bar code, and in older days as whatever numbering system a media publisher used. It could be the most reliable way to indicate the exact source of a recording, given that the same Album Name could be used for both CD and vinyl versions, and even for alternate or unrelated recordings.
At first I thought of using the Content ID field, but it's not editable so not useful for Catalog Number. However, I don't find Content ID mentioned in MC's Help or in the Wiki, and searching the forums I don't find it discussed. What is it used for? Which perhaps raises a need for one place (the Wiki?) where every standard library field is listed and its purpose defined.
