The cyberspace 'earnings' I get from Linux come in the format of having a Network of people that know me and trust me, and that I can depend on in return.
Sometimes, I actually end up doing three or four different versions of one song, and sometimes, those versions can be done very differently. They can be very laid back, downtempo, or sometimes the same song can be quite uptempo. But it is always the same melody and chord progressions.
