Audioblogs, blogs that discuss music and offer free downloads of those songs, have become an exception to the music industry's dislike of file-sharing:
"This is not, you might think, a development the beleaguered music
industry can be watching with enthusiasm, but you'd be wrong. An New
York University study published in February, Does Chatter Matter?,
found that the volume of blog posts about a new album can significantly
affect sales. Many record labels now view the audioblog as a vital
marketing tool, and a euphoric plug on Brooklyn Vegan is more valuable
in certain cases than a five-star review in Q. ('Certain cases' is
worth noting; most blogs shy away from the mainstream, favouring
obscure bands whose fans will also favour less obvious sources of
information.)
In contrast to their disreputable cousins,
file-sharing networks, MP3 blogs don't attract much legal attention. No
one has been prosecuted for posting individual tracks. The most serious
injunction a blogger is likely to get is a polite 'take down' notice,
usually for posting material too far ahead of release. 'In fact,'
according to Scott Wright, who runs the London-based blog Pinglewood.com, 'almost everything I post now is something I've been sent or asked to post by record labels or artists.'"
It's interesting to see the music industry adopt a more nuanced approach and realize that closing off all access to music is not helpful to sales and more discussion of music and sampling of music (in the give-it-a-try sense) is how people could get interested.
