so you know how you can have a checked list of songs in iTunes?

is anybody aware of a way to do something similar in the metro music app? I don't want to play ALL of my songs, but I really like the nifty integration it has with the os. part of me is hoping I won't find a solution so I'll have to figure out how to parse itunes files to create a list of checked songs and send them to/get them from my server. but the rest of me knows I don't know how to do that.

but I digress! if anybody knows how to accomplish this or something similar, please share!
