sfcfran, your analogy while interesting is highly exaggerated and not completely accurate. Musical content just like other "data" is transmitted through packets and there are mechanisms along the path to ensure the integrity of the packets. Its not like a "wave" is traveling through air and going through wires and cables, etc. Also, in most if not all cases, satellite is not in play for music content transmissions but as a reference, many get suer high quality video content through the same path you described without even a single frame out of pace.
Sorry about the tangent.
