If you like getting those little Notification Center alerts when things happen, here's a way to get even more. iTunification gets information from iTunes when tracks change, and funnels this into Notification Center, so you can get a banner to see what the next track is.
This certainly isn't new, as GrowlTunes has been able to do this for a while (if you use Growl), and I get notifications from CoverSutra, an iTunes controller. On top of that, I'd be willing to bet pretty much anything that the next major update to iTunes has Notification Center support. But in the meantime, if you want simple banners to tell you what's playing, this is a good solution, and it's free.
