I recognize that I'm a fossil, but I remain very much an album-driven consumer. If I hear a song I will buy (or download, depending) the album simply because I find most singles off albums do not represent the best work of that artist. I've also consistently had miserable results with Spotify, Grooveshark, whatever. If I want to show someone new music, it's never on any of those services. Maybe that makes me a crazy outlier or something, but the only service that has my music is Google and that's only because I put it there. I was trying to get a friend to play a few tracks from Google's vast collection and they had none of it. I give Drip.fm $15 a month and don't feel even vaguely bad. I used to give emusic $12 a month until they traded all of their indie labels for access to Sony... that was about the time everyone stopped giving a shit about eMusic. I think Lefsetz is right: it's gonna be about small bands that can hustle. I have no problems knowing that the bands I listen to will never play anything bigger than a genre festival.
I'm with you. Just picked up a handful of albums and I'm (surprisingly) loving everyone of them. Not every track in great but there are many tracks I wouldn't have gotten into if I had just bought the song that got me interested. It's not new music that I'm missing from the services, it's mostly older albums that I can't find, probably just 10% of the time but that 10% is enough for me to feed at a different trough.
Back in the day (which, I can't quite say) I imagined an album was to a single as a novel was to a short story; an interconnected set of smaller movements thematically arranged into a longer work greater than the sum of its parts. Singles felt like a little fragment of the whole thrown out into the world in order to tempt the audience to engage with the musicians' larger vision. Not all of them, of course, but the ones that stay with me. Then again I sat through Tubular Bells and Animals and a few other albums that didn't even bother with track breaks, so I'm probably an outlier too.
