I don't know the song, but I did enjoy listening to this, even though I think the main background sawsynth is alittle too dominating. Maybe some playing around with the cutoff and reverb with it could help with some variation for that. :)
It's funny to be the one to show you how to make music with FL Studio, then watch you hit the top of the popular charts. Great job on that, my friend!
Keep up your stuff. :)
