A lot of the music posted is a single here, a single there - often before official release. Sometimes it isn&#x27;t weeks until that single (or larger album) is available for purchase.<p>Plus, for the electronic&#x2F;DJ side of things, many of the tracks posted are remixes which aren&#x27;t ever for sale (it seems). But from a scale standpoint, you would think that there might be <i>some</i> sort of revenue opportunity there.
