During testing of the Song Lyric Lookup feature, some questionable results were observed. Specifically, when searching for songs by the artist A Blaze of Feather, known to be absent from azlyrics, the lookup returned unexpected matches instead of null results.
For example, the track “Dust in the Wind” by A Blaze of Feather incorrectly matched “Lost Girls” by Cocorosie. Similarly, “More Than I” was matched to “Look at Me” by Lil’ Wayne, “Seasons” to “Awake Like An Owl” by Andre Nickatina, and “We Were Here” to “An Orgy Of Critics” by Say Anything.
This testing was conducted with tracks from an album of 13 songs by A Blaze of Feather. Out of these, four tracks produced these seemingly random matches, while the remaining nine returned blank results as expected. The tracks are cleanly tagged and include the itunecatalogid, verified against the iTunes API:

To improve the accuracy of the song lyric lookup, especially in cases where a direct match is not found, implementing a percentage-based match threshold could be beneficial. This might help to avoid misattributions and provide more reliable results when users are searching for song lyrics. It appears that even using quotation marks around the artist name in the search query does not significantly enhance the quality of the search results.
