How about writing the name of the singer into a database field, e.g. a Collection or Custom and configure "Song Title Formatting" so that the name of the singer is shown?
I would display the singer's name as the first field in "Caption" so it is shown leftmost in the second line of every song. Additionally having the soinger available in a database field allows flexible ways to filter by singer, e.g. exclude all songs of a singer in case he or she is not available.

Thanks for your input but I don't want to clutter the collection with extra text. Do you not agree that coloured text is an excellent way to solve my problem?
