Drag-and-Drop Links to iTunes
Rather than downloading audio files in your browser, locating them in the Finder, and then dragging them to iTunes, why not drag-and-drop the links to them on the iTunes Dock icon?

The download process would be handled by iTunes.

If the audio file’s Name tag could not be read while downloading, the link title text would be displayed until the download completed. The title text would remain if the Name tag were empty. The actual audio files would be saved in the user’s iTunes music library location.
If you decided to add the site to your audio feed collection, you could drag-and-drop the syndication link to iTunes rather than having to use the “Advanced [menu] -> Subscribe to Podcast…” dialog.
Being able to drag-and-drop movie links to QuickTime Player would also be nice. Movie files could be downloaded to either ~/Movies or the browser’s default download location.
Naija Jams has good samples of Afrobeat and Highlife music from Nigeria. The Sade song shown in the mockup is no longer available (they probably realized it was a copyright violation!), but it can be had by purchasing “Red Hot + Riot: The Music and Spirit of Fela Kuti” at Amazon.


Man, you’ve got some great ideas. I sure hope someone from Apple is reading this stuff.
