I've just downloaded song 3.
I like it - it reminds me a little of Talk Talk who I liked in the 80s (showing my age now !)
I tend to agree with some of the others in that I think the pitch bending on the lead gets a little bit tiring after a while.
Have you considered doing some vocals on it, instead ? This could turn into a catchy synth pop tune with a good vocal hook - just ready for the 80s comeback, if it ever happens
