So, I'm back!
And yeah, the rest of the songs aren't as horrible as Shooting Zeros, but still, as a whole I have a quite a few problems with the music you two compose.
So I guess instead of commenting each song individually, I'll just make use this to comment on the music overall.
First! The volume balance between the instruments in everything I've listened to (maybe the 15 most recent songs and a few from several years back) is much too similar--meaning the drums are about as loud as the bass which is also as loud as the synth which is also as loud as the piano (and you see what I'm getting at). Because of this, everything tends to mush together and nothing stands out. While on this subject, I feel like the overall sound quality of the songs had something missing; they felt "fake" or "plastic," almost. Maybe just some sound editing here to give more depth to the music (as in stronger bass and treble).
Second! It sounded like every instrument was doing it's own thing in some of the more "full" songs, I guess is how I'd put it. There was no structure or support for the "lead," which ought to catch the listener's attention. Pretty much every good song works this way. Other instruments will hang back in what they play and how they play, whether it be in pop (for vocals), metal (for guitar), or electronica (either the rhythm or lead synth). In your guys' case, even if each of those solo-esque parts were catchy, there would be no way to hear it because it would get lost in the cacophony.
Third! Now it may be a contributing factor of the aforementioned issues, but a lot of your melody progressions sounded very forced. Like you felt "oh, I think we've been playing this melody too long, we should switch to a new one in an attempt to keep it fresh," without taking into account how they should transition into one another. For example, if you don't intend to change the mood of the piece (think from verse to chorus), then don't change too much in the piece and milk it for what it's worth. Now, that isn't to say you should keep to one feel because then the song gets repetitive (i.e. Shooting Zeros), but just stick to contemporary song structure if you intend to use contemporary instruments. Make the sections distinct in sound! Start on different chords! Use different modes!
I think that's everything I wanted to cover. Hope that wasn't too messy to read.
Cheers!~
