Yesterday in my post Killing the "WinFS is About Making Search Better" Myth I wrote

Now this isn't to say that there aren't some searches made better by coming up with a consistent way to interact with certain file types and providing structured metadata about these files. For example a search like

Get me all the songs [regardless of file type] either featuring or created by G-Unit or any of its members (Young Buck, 50 Cent, Tony Yayo or Lloyd Banks) between 2002 and 2004 on my hard drive

is made possible with this system. However it is more likely that I want to navigate this in a UI like the iTunes media library than I want to type the equivalent of SQL queries over my file system.

I just found out that I can already do stuff like this today in iTunes. I can create a playlist by querying based on artist, song name, genre, year, rating, album and a lot more. I've been wishing for this functionality ever since I bought an iPod. Apple fucking rocks. I'll never use WinAmp again.
