The mix on the first track sounds like it was fed into LANDR with too much high end (or LANDR just sucks, haven't ever used it so I don't know exactly what effect it has) or just was sent to Soundcloud at too high a volume. I tend to leave about -0.5 db of headroom on mixes that I post to soundcloud and bandcamp just because I seem to get some artifacts in the high end if I dont. I would also just recommend rolling off the high end on the drums with a filter - I would say somewhere around 20K is a good place to start.

Part of the issue may be that there's a fake record crackle going on the whole time, which has weird interactions with the mix when layered over the full ensemble.

Sidebar: are you using a Korg Volca Beats for your drums? I only ask because I have one, and that snare sounds veeerrry familiar. In any case, I would consider mixing in either a clap or a live snare sample to beef up the snare a touch.

Dead on. The drums here are all volca. Last track was too (except the cymbals). I never thought about layering a clap with the snare. That's a nice trick since the volca snare lacks a lot of usable versatility.

The lofi pad is also a volca- the volca FM. It's the organ setting being run through the distortion on an amp, which makes it a bit harsh. The same trick was used on the other track too, but with a nicer amp that has tubes n stuff.

The bass is volca FM too. Basically volcas all around except for the samples.

I haven't looked at the floaty delay. I'll have to check it out. The reverse snare mixing tip is also super useful. All the tips are super useful. I've got ample access to stuff to make quality recordings but not the know-how to do it.
