i like this song but due to the fact its almost bass-less it spreads an empty feeling..
if your going for a house/electroish song, ever again (like this song) with sharp leads you really need, no you HAVE to have more bass.. otherwise it feels like you put an EQ on and cut the bass..
bass isnt necessarily a 'filler' to make a track sounding fuller but in this case it is.
anwho i really like the leads in this and the simple/basic notes you used to do the melodies.
its catchy, simple and will always work.
