For instance with a release with the inline search in edit search (citation from another ticket) « BTW it was difficult to select the correct "Shades of blue" release among dozens of identically named "shades of blue" releases. »
Maybe release artist, year and catalogue number could be displayed to help selection ?
The same applies with the relate to release ajax search (it's the same module I guess).
Other entities seem to already have some minimal disambiguation info (artists for works etc.).
