I figure given the Ruin is partially based off of The Thing in how it operates, most of this race's tunes are very 'unsettling'; Most of their music and visuals would be very "silent-hill"-esque versions of other existing races.

http://youtubedoubler.com/?video1=PZgtQ-pGUQ4&start1=0&video2=J_G-_Ill2S4&start2=0&authorName=spook - Disturbing track.

https://www.youtube.com/watch?v=_AWIqXzvX-U - Another 'calm' tune base for the Fragments

https://www.youtube.com/watch?v=XR7WTrZ97Kc - Fragments are aware of how the universe's cruel nature works; They ARE it, after all.

https://www.youtube.com/watch?v=nWnUuosQwZY - A calm tune.

https://www.youtube.com/watch?v=XYrQC-jWMFM - A relatively upbeat tune.

https://www.youtube.com/watch?v=UFttpybk1zw - A calm tune, with disturbing droning.

https://www.youtube.com/watch?v=baKA1B5Ymuo - Another tune

https://www.youtube.com/watch?v=HwcaK6KKlWg - Fragment Tech is basicaly non-existant, and when it is, it's nasty, corroded, tetanus-and-tinitus infectious rusty metal fused to flesh that barely functions at all. This song encompasses this and serves well for any 'prelude to a battle' music.
