A compilation sits neatly under one album title, yet its tracks may belong to several performers. If your collection note stores only an umbrella label, the person you remember hearing can become surprisingly difficult to find later.
Separate grouping from credit
In a personal index, use one field to keep the album together and another to record the credited performer for each track. The names of software fields vary, so check how your library handles album grouping before making a large edit.
For an invented example, a collection called Evening Windows might contain tracks credited to three different groups. The album title identifies the release; the individual credits identify who is associated with each entry. Neither replaces the other.
Copy the credit from the source you have
Read the sleeve or booklet and retain meaningful collaboration wording. If a credit is unclear, add a source note rather than assigning the whole track to the first familiar name. Distinguish what your copy prints from extra information gathered elsewhere.
Try a five-track practice list. Search for one performer, then return to the complete album order. If the list supports both tasks, the fields are doing useful work.
Keep sorting decisions reversible
Do not rewrite a displayed credit solely to make an alphabetical list behave. Our guide to display names and sort order offers a way to separate that problem. Keep the original wording available when trying a new convention.
The finished note should help you answer two ordinary questions: which album contains this performance, and which track was the one by that group? A small amount of structure preserves the variety that made the compilation worth keeping in the first place.
