GimmeSomeTune is a small tool that makes iTunes a bit better.
First of all, it's a quite useful iTunes controller, that enables you to define your own hotkeys for jumping through your songs and changing the music volume. On every song-change the song's name, album artwork, rating etc. can be displayed in a small and highly configurable window.
You don't have any album artworks? No problem! GimmeSomeTunes will download missing artwork together with the lyrics for your songs.
I'm using Drupal to power this site. It's not as user-friendly as -- let's just say WordPress -- but very powerful and easily extendable through well-designed PHP modules or even rude hacks inside your posts.
One nice feature for site admins is its status report page: At a glance you can check if your Drupal installation is in good shape, when the last cron maintenance tasks was run, and how many form submissions were blocked by CAPTCHAs.
