I've spent more time on the site today than I have any other day in the past.<p>My problem before was that I would quickly scan through artist names/song titles and listen to one here or there and then move on.  Now I give almost every song a chance before I go to the next.  I get instant visual connection with each artist via the high-res pic, and i'm diving deeper into learning about artists with the little bios and pics that pop up during playback.<p>This is a win for music discovery UI's, even though it may be a loss for the social network aspects of their site.
