The problem w/ #netaudio as a term is that the current world is vastly different from when that term originated. #NetNativemusic or #netnativeaudio includes any shareable license, not limiting to #ccmusic and doesn't limit just to #netlabels
Like netaudio, Netlabel fails as a term since many musicians release sans label. While @wiloma's definition of label seems technically correct to me, it not only fails for the same reasons as netaudio but also folks just dont intuitively view labels his way
