The name of the song is Lux Aeterna....
But that's not the reason I'm 6'ing this.
The idea was there, and could have been very good, but there were some things working against you. The beat for this song is just too simplistic, and it was patterned in a way that didn't flow well with the song at all. Additionally, the synths that came in at :48 were rather loud and harsh sounding.
Work on making a more coherent beat pattern, and lower the volume on your synths a bit, and this song will sound much better.
