I took the liberty of asking the folks on another SQ-specific forum. Sarah's composition can be found in this month's "Meditation" playlist of the Krisworld entertainment system.

I'm not flying anywhere on SQ this month so can't take a picture of the actual IFE screen, but a couple of screen captures from the track listing in SQ's iPhone App can be found here (Links to external site).

Hopefully someone else (Do you have another flight coming up, Singapore_Air?) can locate that playlist on the IFE and take a picture!

Very nice piece of music, Sarah!
