In a press conference attended by /Film's Jenna Busch, James Gunn revealed the song that has kept missing the cut for an appearance on the “Guardians of the Galaxy” soundtrack.

Gunn writes the songs he plans to use in the films into the scripts, which is a testament to both Marvel's music rights budget and the appeal of being on a “Guardians” soundtrack.

These mixtapes guarantee a popularity boost for the artists they feature. Gunn admitted, “Honestly, it has become strange because the first two albums were huge hits.”

Gunn added, “They changed the lives of some of these artists who now have big hit songs, and so I know that when I'm choosing a song [it’ll] be something a lot of people [hear].”

The one song that fans haven’t heard in the film’s musical compilation because it has narrowly missed the field over and over again is Nick Lowe's 1978 pop tune “Cruel To Be Kind.”

While Gunn didn't say why Lowe's hit didn't quite make the selection, it sounds like the tune is in good company on a very lengthy list.

Gunn shared, “I keep a list of like hundreds of songs that would be, you know, ‘Guardians 3’ type songs,” adding, “There's things I have on lists that I could never use!”

The filmmaker said that “Cruel To Be Kind” has appeared “on every list that I've had for the movies, and I just never found a place to work it in.”
