Can we have a thread about this?

How do you guys organize your anime related music?
It bugs me how many series dont have official, well compiled soundtrack albums.
Or how so many music related anime don't have proper albums to go with it.

Although the albums arent amazing, I decided to get the Idolm@ster greatest best albums as it had pretty much all the vocal songs that mattered.
I really need to get some k-on soundtracks, but everything is either in singles, massive boxsets, or mixed in with random BGM. So I'll probably just grab the best stuff and make a fake album.

post your stuff, and how you do it
