Interest in new audience note for graphic audio and booktrack titles?

We would like to know if there is interest in adding a new audience note that identifies titles that have music and sound effects as part of the recording. We recently noticed that the ISBN for DB125411 "Wild Thing" is a Booktrack edition. If a new audience note is added we would do our best to identify existing records to add the note to.

Would you be interested in having a way to identify these titles? What would that look like ideally for you? Do you think this would benefit RAs and patrons?

What is Booktrack? Unabridged audiobook plus music soundtrack
"Booktrack is an immersive format that pairs traditional audiobook narration to complementary music. The tempo and rhythm of the score are in perfect harmony with the action and characters throughout the audiobook. Gently playing in the background, the music never overpowers or distracts from the narration, so listeners can enjoy every minute. When you purchase this Booktrack edition, you receive the exact narration as the traditional audiobook available, with the addition of music throughout." (as described by Audiobookstore.com ) 

What is Graphic Audio? Dramatized adaptations with full cast, music and sound effects
"GraphicAudio® is an award-winning audiobook entertainment company based out of Rockville, Maryland. Since its inception in 2004, GraphicAudio has published nearly 2,000 dramatized adaptations and more than 235 different series in a wide variety of popular genres. All titles are produced in the unique and vivid A Movie in Your Mind® audiobook entertainment format, featuring full cast dramatizations richly scored with cinematic music and layered with immersive sound effects and design." (as described on the GraphicAudio website )

It would be just like searching for any other subject from an audience note (male narrator, female narrator, for grades..., etc.). I suspect we would backfill this by searching for the publisher.
