So this is something the music companies should have done. Sony and Universal have both put big chunks of their video libraries up on youtube. I realize a decade ago when they were in Napster hell there wasn't a youtube, but they could have done something like this on their own sites.
I'm not sure if I want to get the Katy Perry album, but being able to listen to parts of it this way? I'm a HELL of a lot more likely to than I would have been without it.
