I throw all my music in iTunes as an organization basket of sorts, as I have for ages and where I cannot see any of the artwork (Apple U S*ck), .. then I use this as a frontend, Plex kicks ass so far, for everything (movies of course).. I love it.
Slick, minimal player. Not a bad first effort, but the functionality is super limited. I get that it's meant to be a barebones player, but hope they take it a bit further.
