Ok, this is very cool. Well, don’t ask me why, but I like the 5-leg version way better. I can see it more prone to polyrhythms. 
If you like it too, we can stick to it.
However…
We should use a font with a free license, for legal reasons and to be aligned with our values. I mean, I don’t think anyone will sue us after identifying the font family by looking at the logo, but I believe all of us will feel better forever if whenever we look at that logo we don’t get a GAFAM reference in our minds. 
Well, maybe, but not urgent or really necessary. The bootstrapping ends tonight, and then we’ll start a more calm beta phase. If you/someone could provide the square and rectangular versions of the logo, then I can add them, and we can fine tune if needed.
Square
Use a square 120 × 120 image
Rectangular
Use a wide rectangular image with a height of 120 and an aspect ratio greater than 3:1
SVG if possible. We need transparent background and zero pixel margins (the icon touches the canvas frame). Orange version for sure, green version nice to have.
Oh, for the rectangular version we need to resolve the words problem. Based on @prinlu and @unspeaker comments above, I suggest
soc:music:net
Not cutting “music” so it’s very clear what this is about. “soc” and “net” are abbreviations that are popular to a certain degree, or at least not critical if you don’t get them immediately. Here too we could change if better ideas come. But good enough for a beta?
