As is probably true for many other people too, it changes for me quite frequently...
But I've had one song since the start of this year, which I
still can't get enough of.
"Imagine" by a band named Brunch.
It's in Korean (

), but it's the music that goes with a short series I watched. I then downloaded it, and still love it. >D
Then, of course, I saw the 4th last showing of the Broadway show "Wicked", in Melbourne (Australia). I got the soundtrack, and that's just another set of songs which I find just
beautiful.
To anyone who knows the Soundtrack, I've learnt about half of "The Wizard And I" on Piano. God it's fun to play.

Anyway, yea. Can't get enough of that soundtrack either.
