WOW

As simple as this may be, I think it definitely deserves a 5/5 just because of the saw that you chose and because of the filtering effects on the pads and that melody of that saw. I am truly crazy about filtering effects. I use them in all of my songs from now on now. I just LOVE that flanged/phased synth-saw you used near the end. Try to put some more of the beginning saw in there too. Yno, some melodies to fill up those empty spaces =)

Try to lower the repetition though, That is my only critique
