It appears that Alfred doesn't find/catalog new music. I tried playing a recently purchased an album on iTunes, but I can't navigate to it using the mini-player. I’m using Alfred v2.0.1 (173) and OSX 10.8.3 (but I couldn't do it on previous versions of OSX or Alfred as well). Below is a picture of the mini-player not finding Lindsey Stirling even though it shows her song playing.
