I sort of agree with the utterly absurd side. As musicians we strive for the opportunity to "play" in front of people, to be heard by as many as possible, for someone without the desire to play an instrument to want to listen to our music.
Beck may be a little self-righteous with this effort. I know he's not as popular these days and when he was popular album sales were a little better since the social media hadn't gone viral and the one song download wasn't available but I'm afraid this tactic may end up backfiring. Seriously, who's going to buy a book of sheet music to download into their iPhone or iPod when you can't listen to it. Sorry I just don't get it, isn't the purpose of creating and recording music so your fan base can enjoy it by listening to it.
I know the hard core musician/artist here must be saying, wow, cool this dude is totally rad man, can you believe the creativity behind this....we'll see how Billboard receives it.
the same people who buy $3 bottled water, $5 dollar coffees and $500 devices that allow themselves to be completely engulfed with technology...
the average consumer would buy it if enough social media buzz propagated it in a certain light.
i think it is an amazing idea.
not sure how it would play out.
it seems to me that it would benefit musicians the most; they would learn to read music for one; more people might learn to record at home.
it may inspire fans of an artist to possibly learn to play an instrument for the sole reason of becoming a part of the creative process of their beloved artist.
record companies would suffer i guess...

it could also be a very short lived gimmicky -type idea with a small window of huge profit; i dunno...
not sure how it would play out though but what an interesting concept.
