A record may sit comfortably in two parts of your collection even though the sleeve uses only one genre label, or none. Your catalogue can accommodate that without making a personal filing choice look like a publisher’s claim.
Create separate fields for wording transcribed from the object and tags you assign for finding it again. Preserve the printed wording accurately in the first field. In the second, use terms that make sense for your listening habits.
Imagine searching for records you play while drawing, or for albums where you want to revisit the percussion. Those tags serve a different purpose from broad genre labels. They can overlap without requiring the album to occupy several physical shelves.
Try the tags on five records before applying a large classification system. If you cannot remember which of two nearly identical tags you used, combine them or write a brief definition.
Avoid turning a personal label into a claim about the musicians’ identity or intentions. “My rainy-afternoon selection” reports your use; “music intended for rain” would need evidence of a different kind.
Review tags as your collection and listening change. A useful catalogue should make rediscovery easier, not force every record to defend its place in an elaborate set of categories.
