Netlabels
The Wikipedia definition of a netlabel is:
A netlabel, also called online label, web label or MP3 label, distributes its music in digital audio formats (mainly MP3 or Ogg) online. Netlabels often work like traditional record labels to produce and promote music projects (such as albums or compilations). Most employ guerrilla marketing to promote their work. Few netlabels earn money for participants.
The music that is reviewed on this site is either released on such a netlabel, or released online by the artist him/her/themselves. The music reviewed here will most of the times be available for free download. On some occasions, the label or artist may require payment to download the music.
