A title on a wish list can outlive the reason you added it. Six months later, you may remember wanting the album without remembering whether you wanted a particular performance, edition or piece of packaging.
Write the reason beside the title
Use a short concrete note: “Contains the performance mentioned in my programme” or “Compare this arrangement with the version already on the shelf.” A reason makes the list easier to review than a row of unexplained wants.
Record the identifier you actually know. If you have only heard a recommendation, say so. Do not silently convert an uncertain reference into an exact edition.
Separate interest from a purchase decision
Add a question field for anything unresolved: track list, condition, compatibility or whether you already own the same recording elsewhere. The list can hold curiosity without implying that every entry should become a purchase.
You can also add a review date. An item that no longer interests you can leave the list without being treated as a missed opportunity.
Check your own shelf first
Search the catalogue by performer and work as well as title. A compilation may already contain the recording you wanted to explore. Combine the list with a week of rediscovering your own records. The best result may be a useful new listening session rather than another parcel.
