Embedded Bliss

So I have put out a few new songs, two of which I would very much enjoy feedback on.

The first one is called "Embedded Bliss" and is already a favorite one among my friends. I like it because it features a very mathematical echo that actually never quite dissipates. With this, the echo actually is just slightly off beat to produce a very slight longer sounding echo each time. It is very very subtle, but is a fun, happy song anyway:

The second one isn't as "happy" though I would neither call it sad. I put a certain effect on the piano that I have fallen in love with... It is actually a bit repetitive, but at the same constantly changing with a certain "vox-ish" instrument. It is supposed to hone in on the fading in and out of certain dissonances and chords. I actually like this one quite a lot, and would love feedback on this one so I can know what to change to make it even just that much better. It is called "Distantly Dissonant":

And I actually do have a third one, but really it was just a super instrumentally experimental track. I feature live drumming that I did in it, and need opinions on sound (dB) levels:

Thanks!!!
