We discovered some hits with programas/ultramixNN.html pattern, likely remnants of the past.
We however like music also, and the Creative Commons philosophy is applicable to musical works no worse that to software programs. Programmers know source code, computers and mobile phones, and at the end binaries for the end user. Musicians know notes and chords, drums and guitars and the sound tracks for the end listener. Hence we think we can at least place some links here.
Depending on who you are, you may also like more visualizations.
If you offer your own music under Creative Commons Attribution Share Alike license, or simply know a good site, feel free to append your address here as well.
