UPDATE (1/6/2011): I Love Stars is now available exclusively at the Mac App Store for the price of $1.
I'm happy to announce that I Love Stars 3.0 is out! Please consider it my small Christmas present to fellow Mac users as it continues to be free.
I Love Stars 2.0 was a little menubar application that did just two things: 1) show you the star rating of iTunes' currently playing song and 2) let you click to set a new rating.
Version 3 keeps to its simple mission but adds two important new features:
Unrated song alert
When you're about three quarters of a way through an unrated song, ILS now alerts you by flashing in the menu bar and also by playing a sound effect.
You can assign custom keyboard shortcuts for changing the ratings now. I was using QuickSilver's iTunes plugin for this but I found QS to be too slow to react sometimes.
Both of these new features can be customized in the app's new preferences window. To get to it, you need to right click on the menu bar to open the menu.
There are other changes under the hood but you probably won't notice them. The animation has been rewritten from scratch and some obscure bugs and memory leaks have been fixed. It should be stable as I've been running it for months and months now, but if you find anything, be sure to let me know.
Cheers and happy holidays.
