We like to Dance

I like the echo sounds as well.  And I agree, some duty cycle changes would be nice.  I think the introduction is too long.  And a bit repetitive.  Either repeat less before it changes or make what is repeated more complex so that it requires the listener to hear it more times before they fully grasp it, thus holding their interest longer.  You have some good sounds going on here though!  I like the little stereo echo buildup back into the beat around 3:20.  Around 3:50, the dissonance is interesting, and I love dissonance, and it sounds really really cool with the echo.

I think the main thing is to make it less repetitive.

I like this!

I like this soft mello and heavy drums

It takes a bit too long to get going and there isn't much going on while it's building up. A bit too repetitive for me melody-wise. It'd be cool to hear some duty cycle changes or something on that sustained bass note. And maybe a bit more variation in the noise channel. Maybe a key-change.

I like the echo sounds.
