To date, the album is difficult to find, as it wasn't sold in stores or distributed massively beyond being included with Killer Instinct.
The tracks from Killer Cuts can be unlocked for in-game use in Killer Instinct for Xbox One. Additionally, the album was digitally re-released on October 14, 2014, as part of a double album set with the Killer Instinct: Season One soundtrack. 
Tracks 16-29 are blank tracks lasting four seconds each that lead into the hidden track 30. It is not known to this date why Nintendo or Rare decided to do this, but it was common for most to simply take the CD out after the 15th track. There is an issue of Nintendo Power that revealed the hidden track #30 with the Humiliation theme. In the re-release, the blank tracks were removed, and "Humiliation" was listed normally with the other tracks.
